SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K (the “Form 10-K”) contains forward-looking statements that can involve substantial
risks and uncertainties. All statements other than statements of historical facts contained in this Form 10-K, including
statements regarding our future results of operations and financial position, business strategy, financing arrangements,
prospective products, product approvals, research and development costs, future revenue, timing and likelihood of success,
plans and objectives of management for future operations, future results of anticipated products and prospects, plans and
objectives of management are forward-looking statements. These statements involve known and unknown risks,
uncertainties and other important factors that may cause our actual results, performance or achievements to be materially
different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,”
“anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential,”
“would” or “continue” or the negative of these terms or other similar expressions. The forward-looking statements in this
Form 10-K are only predictions. We have based these forward-looking statements largely on our current expectations and
projections about future events and financial trends that we believe may affect our business, financial condition and results
of operations. These forward-looking statements speak only as of the date of this Form 10-K and are subject to a number of
risks, uncertainties and assumptions described under the sections in this Form 10-K entitled “Item 1A. Risk Factors” and
“Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this
Form 10-K. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be
predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements
as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be
achieved or occur and actual results could differ materially from those projected in the forward-looking statements.
Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it
is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do
not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new
information, future events, changed circumstances or otherwise. Thus, one should not assume that our silence over time
means that actual events are bearing out as expressed or implied in such forward-looking statements.

You should read this Form 10-K and the documents that we reference in this Form 10-K and have filed as exhibits to this
Form 10-K, completely and with the understanding that our actual future results may be materially different from what we
expect.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject.
These statements are based upon information available to us as of the date of this Form 10-K, and while we believe such
information forms a reasonable basis for such statements, such information may be limited or incomplete, and our
statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant
information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these
statements. These statements should not be relied upon as representing our views as of any date subsequent to the date of
this Form 10-K.

RISK FACTOR SUMMARY

We  are  providing  the  following  summary  of  the  principal  risk  factors  contained  in  this  Form  10-K  to  enhance  the
readability and accessibility of our risk factor disclosures. We encourage you to carefully review in their entirety the full
risk  factors  set  forth  in  the  section  of  this  Form  10-K  captioned  “Item  1A.  Risk  Factors”  for  additional  information
regarding  the  material  factors  that  make  an  investment  in  our  ordinary  shares  speculative  or  risky.  These  risks  and
uncertainties include, among others, the following:

● We have incurred significant losses since inception and anticipate that we will incur continued losses for

the foreseeable future, and may never achieve or maintain profitability.

● We  will  require  additional  capital  to  fund  our  operations,  which  may  not  be  available  on  acceptable

terms, if at all.

● We may not have sufficient cash flows or cash on hand to satisfy our debt obligations or covenants under
our  financing  arrangements,  or  we  may  not  be  able  to  effectively  manage  our  business  in  compliance
with such covenants.

● We are heavily dependent on the success of our Most Advanced Product Candidates (as defined in “Item
1A. Risk Factors”), which are still in development, and if none of them receive regulatory approval or
are successfully commercialized, our business may be harmed.

● COVID-19 has impacted and may continue to impact our business, and any other pandemic, epidemic or
outbreak  of  an  infectious  disease  may  materially  and  adversely  impact  our  business,  including  our
preclinical studies, clinical trials, manufacturing capabilities and regulatory approvals.

● It is difficult to predict the time and cost of product candidate development on our novel gene therapy

platform. Very few gene therapies have been approved in the United States or in Europe.

● Because gene therapy is novel and the regulatory landscape that governs any product candidates we may
develop  is  uncertain  and  may  change,  we  cannot  predict  the  time  and  cost  of  obtaining  regulatory
approval, if we receive it at all, for any product candidates we may develop.

● Clinical  trials  are  expensive,  time-consuming,  difficult  to  design  and  implement,  and  involve  an

uncertain outcome. Further, we may encounter substantial delays in our clinical trials.

● The  affected  populations  for  our  product  candidates  may  be  smaller  than  we  or  third  parties  currently

project, which may affect the addressable markets for our product candidates.

● We  and  our  contract  manufacturers  for  plasmid  are  subject  to  significant  regulation  with  respect  to
manufacturing  our  products.  Our  manufacturing  facilities  and  the  third-party  manufacturing  facilities
which we rely on may not continue to meet regulatory requirements and have limited capacity.

● Enacted and future healthcare legislation may increase the difficulty and cost for us to obtain marketing

approval of and commercialize our product candidates and may affect the prices we may set.

● We  are  subject  to  government  regulation  and  other  legal  obligations  relating  to  privacy  and  data
protection.  Compliance  with  these  requirements  is  complex  and  costly.  Failure  to  comply  could
materially harm our business.

2

Table of Contents

● We  face  significant  competition  in  an  environment  of  rapid  technological  change,  and  there  is  a
possibility that our competitors may achieve regulatory approval before us or develop therapies that are
safer or more advanced or effective than ours, which may harm our financial condition and our ability to
successfully market or commercialize any product candidates we may develop.

● We depend on proprietary technology licensed from others. If we lose our existing licenses or are unable
to  acquire  or  license  additional  proprietary  rights  from  third  parties,  we  may  not  be  able  to  continue
developing our product candidates.

● If we are unable to obtain and maintain patent protection for our technology and product candidates or if
the  scope  of  the  patent  protection  obtained  is  not  sufficiently  broad,  we  may  not  be  able  to  compete
effectively in our markets.

● We may need to expand our organization, and we may experience difficulties in managing this growth,

which could disrupt our operations.

● Our future success depends on our ability to retain our key personnel and to attract, retain and motivate

qualified personnel.

ITEM 1.  BUSINESS

Overview

PART I

We are a vertically integrated, clinical stage gene therapy company with six programs in clinical development and 

a broad pipeline of preclinical and research programs.  We have core capabilities in viral vector design and optimization 
and gene therapy manufacturing, as well as a potentially transformative gene regulation platform technology that allows 
precise, dose responsive control of gene expression by oral small molecules with dynamic range that can exceed 5000-fold.  
Led by an experienced management team, we have taken a portfolio approach by licensing, acquiring and developing 
technologies that give us depth across both product candidates and indications.  The Company’s initial focus is on three 
distinct areas of unmet medical need: ocular diseases, including both inherited retinal diseases as well as large degenerative 
ocular diseases, neurodegenerative diseases and severe forms of xerostomia. Though initially focusing on the eye, central 
nervous system and salivary gland, we intend to expand our focus in the future to develop additional gene therapy 
treatments for patients suffering from a range of serious diseases.

We own and operate a flexible and scalable viral vector manufacturing facility in London, United Kingdom that 

we expect can supply our current ophthalmology, neurodegenerative disease and salivary gland clinical and preclinical 
programs through regulatory approval and, should they be approved, provide sufficient capacity for commercial 
production.  Completed in early 2018 and designed to meet global regulatory requirements, including the current good 
manufacturing practices, or cGMP, required by the U.S. Food and Drug Administration, or FDA, our 29,000 square foot 
facility has two cell production suites, three independent viral vector production suites providing multi-product and multi-
viral vector manufacturing capabilities and an integrated, flexible fill-and-finish suite.  In May 2018, we were granted a 
license to manufacture gene therapy product candidates in our cGMP compliant manufacturing facility by the United 
Kingdom’s Medicines and Healthcare products Regulatory Agency, or MHRA.  The MHRA re-certified the facility in the
second quarter of 2020.

We have expanded our manufacturing capabilities with our second, large scale cGMP viral vector manufacturing 

facility and our first cGMP plasmid and DNA production facility in Shannon, Ireland. Coming online in 2022 and 
stretching over 150,000 square feet, it is the first commercial-scale gene therapy manufacturing site in Ireland and is unique 
in its scale and integrated capabilities. The site contains three facilities, one built to be flexible and scalable for viral vector 
production for clinical and commercial supply, in addition, a facility to manufacture plasmid DNA – the critical starting 
material for producing gene therapy products – and thirdly, a Quality Control (QC) hub performing advanced biochemical 
quality control testing for MeiraGTx clinical and commercial programs. We completed the acquisition of the facilities in 
January 2021.  We believe the completion of our second viral vector manufacturing facility and bringing cGMP plasmid 
and DNA production in-house will provide greater flexibility and efficiency as we advance our product candidates through 
development, and should they be approved, commercial production.

We have also established a comprehensive platform for the efficient clinical development of the next generation of 

gene therapies and manufacturing in accordance with cGMP.  Our deep understanding of disease models informs our 
development of potency assays for the cGMP production of our product candidates, and our teams experienced in viral 
vector design and optimization work closely with our process development team to design viral vectors and develop 
proprietary production cell lines for efficient scaling of manufacturing processes. Our wholly-owned facilities have now 
produced GMP clinical trial material for six different indications, using multiple AAV serotypes, including administration 
into the eye, salivary gland and central nervous system.

We are also developing a potentially transformative technology to precisely and specifically control gene therapy 

expression levels via dose-response to orally delivered small molecules.  The aim of this gene regulation platform 
technology is to transform gene therapy into a generalizable delivery mechanism for biologic drugs using a 

4

Table of Contents

small molecule “switch” for temporal control.  We believe the capacity for temporal control of gene therapy products has 
the potential to transform the gene therapy landscape by opening up new treatment possibilities.

Our Pipeline

Our initial focus is on three distinct areas of unmet medical need: ocular diseases, including inherited retinal 

diseases, or IRDs, as well as large degenerative ocular diseases, severe forms of xerostomia and neurodegenerative 
diseases.  Utilizing our product development platform, we have assembled a pipeline of gene therapies to treat these serious 
diseases.  Our criteria for selecting our initial product candidates included:

● unmet medical need;

● high potential for meaningful clinical benefit;

● promising preclinical data using multiple animal models as well as human stem cell derived organoids;

● compartmentalized anatomy of target tissue and the partially immune protected nature of target tissue; and

● understanding of the disease state from natural history studies and detailed long-term characterization of

patients prior to entry into gene therapy treatment studies.

A summary of our product candidates and the status of such product candidates as of March 1, 2023 is described 

below.  We retain worldwide development and commercialization rights to all of our product candidates, with the exception 
of AAV-CNGB3, AAV-CNGA3 and botaretigene sparoparvovec, formerly referred to as AAV-RPGR, which are subject to 
a strategic Collaboration, Option and License Agreement (the “Collaboration Agreement”) that we executed with Janssen 
Pharmaceuticals, Inc. (“Janssen”), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, on January 30,
2019.

Table of Contents

In addition to these clinical and preclinical programs, we have preclinical and research programs in other

indications and novel molecular technologies that we aim to advance into clinical development, including:

● gene regulation—use of our proprietary RNA shape regulation cassette to switch gene therapy expression on

and off with small molecules, potentially transforming gene therapy technology into a delivery mechanism
for a broad array of biologic drugs;

● geographic atrophy age related macular degeneration, or dry AMD—use of gene therapy technology to

introduce light sensitive molecules into rod photoreceptors in order to restore some aspects of vision lost in
this disease;

● other ocular conditions—glaucoma and uveitis;

● Alzheimer’s disease—targeting endosomal trafficking, which is a central mechanism that we believe

underlies Alzheimer’s disease;

● central nervous systems/peripheral nervous system diseases—brain-derived neurotrophic factor gene therapy
for treatment of genetic obesity disorders, as well as the development of gene therapy product candidates for
other central nervous system diseases; and

● inflammatory/autoimmune diseases—use of gene therapy technology for the local delivery of

immunomodulatory therapeutics, including osteoarthritis, gout and certain rare inflammatory disorders.

Our Ophthalmology Programs

Eye diseases are our first area of clinical focus and we aim to provide treatments with durable, long-term clinical 

benefit that will halt vision loss in patients.  We are actively dosing patients in our Phase 3 Lumeos clinical trial for 
botaretigene sparoparvovec for the treatment of X-linked retinitis pigmentosa related to mutations in the RPGR gene, or
XLRP-RPGR.  We also have three Phase 1/2 clinical programs targeting IRDs, including AAV-CNGB3 and AAV-CNGA3
for the treatment of achromatopsia, or ACHM, related to mutations in CNGB3 and CNGA3 genes, respectively, and AAV-
RPE65 for retinal dystrophy related to mutations in the RPE65 gene, or RPE65 deficiency. We have completed enrollment
and dosing in all three of these programs. In addition to these four programs, AAV-AIPL1 has been manufactured and
released for compassionate use under an MHRA specials license in the United Kingdom, or UK, to treat patients with
Leber congenital amaurosis 4, or LCA4, caused by mutations in the AIPL1 gene.  In addition to these clinical programs in 
IRDs, we have preclinical programs that apply novel approaches to both wet and dry AMD, glaucoma and uveitis, as well 
as several other IRDs including retinol dehydrogenase 12, or RDH12, mutation-associated retinal dystrophy.

We chose diseases of the eye as our first area of clinical focus because we believe the eye is ideally suited for gene

therapy for the following reasons.

● The eye is easily accessible and has highly compartmentalized anatomy, which allows for accurate delivery

of vectors to specific tissues using direct visualization and microsurgical techniques.

● The structure of the eye allows for efficient delivery to specific cell subtypes with small volumes of vector,

making the dose per patient much lower than is needed for systemic treatment.

● Anatomical barriers and unique structure of the eye make the immune response to the intraocular

administration of vectors more attenuated than systemic administration.

6

Table of Contents

● Largely non-dividing cell populations in the eye make good targets for potentially stable, long-term gene

delivery and expression.

● The retina, a structure in the back of the eye, is visible and there are many well validated structural and

functional readouts allowing the detailed assessment of the therapeutic impact of the gene therapy treatment.

Our strategy for developing gene therapies targeting eye diseases is to begin with a number of monogenic IRDs 

that are good candidates for gene replacement therapies and expand to more common eye diseases over time.  We have 
taken a portfolio approach to the development of IRDs because, while some of these genetic defects are rare, IRDs as a 
class are one of the most common causes of blindness in working age adults and there are multiple synergies at the clinical, 
regulatory and commercial levels between many of these diseases caused by different gene mutations.

The deep scientific and clinical understanding of IRDs driving our approach to gene therapy development helps us 

to optimize our product candidates for each specific genetic mutation and phenotype.  We develop our viral vectors by 
selecting and modifying proprietary cell specific promoters, selecting appropriate capsids for transfection of target cells 
and refining the vector for efficient production and scalable manufacturing.  Not only does this allow us to synergistically 
target a portfolio of inherited eye conditions, we also believe it has potential to be applied to the development of gene 
therapies for other diseases.

Our longstanding relationships with leading institutions in retinal disease treatment, including the Moorfields Eye

Hospital in London, the University of Michigan Kellogg Eye Center, Massachusetts Eye and Ear, the Medical College of
Wisconsin & Froedtert Hospital and the Casey Eye Institute at the Oregon Health & Science University, provide us with
access to experts whose guidance and insight informs our development strategy, as well potential patients for our clinical
trials.

We intend to leverage our platform to take advantage of the many synergies across our ophthalmology programs,
including identification, diagnosis and characterization of patients, specialized surgical techniques, clinical and regulatory
process, vector production and cGMP manufacturing.

Botaretigene Sparoparvovec for the Treatment of X-Linked Retinitis Pigmentosa Associated with Mutations in the
RPGR Gene

Retinitis pigmentosa, or RP, is a group of IRDs which represent the most common genetic cause of blindness.  The 

condition is characterized by progressive retinal degeneration and vision loss that ends in complete blindness.  RP initially 
presents as nighttime blindness during childhood or early adulthood, progressing to peripheral visual field loss and “tunnel 
vision,” central visual impairment, reduced visual acuity and, ultimately, complete blindness.

RP may be caused by mutations in any of over 100 different genes.  The most severe forms of RP are X-linked, or 
XLRP, with onset in early childhood and rapid progression to blindness generally by the time patients reach 30 to 40 years 
old.  The most frequent mutation causing XLRP is in the retinitis pigmentosa GTPase regulator gene, or RPGR. XLRP 
associated with a mutation in RPGR, or XLRP-RPGR, accounts for more than 70% of cases of XLRP.  There are estimated 
to be approximately 20,000 XLRP-RPGR patients in the United States (U.S.), Japan and Germany, France, Spain, Italy and 
the UK, or the EU5, with a little less than 50% of those patients being under the age of 40 and approximately 200 new 
cases being diagnosed annually.  We believe the availability of a therapeutic option may increase patient identification and 
the estimated prevalence of XLRP-RPGR.

7

Table of Contents

There are currently no approved treatments for XLRP.

Clinical Development of Botaretigene Sparoparvovec

We have an ongoing natural history study in XLRP-RPGR including approximately 100 patients, which allows us 

to collect structural and functional data for up to five years on prospectively defined endpoints, including functional tests, 
retinal imaging and electrophysiological assessments.  We believe access to this large population of XLRP-RPGR patients 
has enabled us to efficiently enroll appropriate patients into our XLRP clinical development program.

 Since XLRP-RPGR is a progressive disease in which the retina gradually degenerates starting in the outer, or 

peripheral, regions of the retina and initially causing “tunnel vision” with final degeneration of the central retina resulting 
in the complete loss of visual acuity and blindness that generally occurs by the time patients are 30 to 40 years old, we 
believe that the central region of the retina, including the macula and fovea, must be preserved to prevent the ultimate 
degeneration to blindness and to retain visual acuity.  To this end, we aim to deliver botaretigene sparoparvovec to this 
central region of the retina.

We conducted a Phase 1/2 clinical trial of botaretigene sparoparvovec in XLRP patients. Botaretigene

sparoparvovec was delivered via subretinal injection of up to 1mL with the potential for the surgeon to use multiple
retinotomies targeting the region of the central retina, including the macula and fovea.

In the dose escalation portion of the Phase 1/2 trial, we enrolled 13 patients, including 10 young adults and 3 

children. After we completed dosing patients in the dose escalation portion of the study, we enrolled patients in the 
randomized, controlled, extension portion of the Phase 1/2 trial. We disclosed six-month data from the dose escalation 
portion of the study as a late-breaker at the American Society of Retina Specialists 2020 Virtual Annual Meeting in July 
2020, nine-month data at EURETINA 2020 Virtual Congress in October 2020 and twelve-month data at the American 
Academy of Ophthalmology, or AAO, 2020 Virtual Annual Meeting in November 2020.  Data from each time point 
revealed that patients treated with low (n=3) and intermediate (n=4) dose botaretigene sparoparvovec experienced 
statistically significant improvement in retinal sensitivity. Nine-month data also indicated significant improvement in 
vision-guided mobility, and at 12-months, six of seven patients continued to show improved or stable vision in the treated 
eye. Each patient was treated with subretinal delivery of botaretigene sparoparvovec in one eye and the patient’s other eye 
served as an untreated control. The primary endpoint of the trial is safety, with secondary endpoints assessing changes in 
visual function at pre-specified timepoints post-treatment. Baseline values were determined in triplicate. 

We disclosed additional twelve-month clinical data from the dose escalation portion of the Phase 1/2 trial as part 

of an oral presentation at the EURETINA 2021 Virtual Congress in September 2021.  The retinal function of ten adult 
males aged 18-30 years with RPGR-associated XLRP was assessed twelve months post-treatment.  For the intermediate 
dose-escalation dose cohort (n=4), intervention with botaretigene sparoparvovec in the poorer-seeing eye altered the course 
of natural disease progression.  At twelve months post-intervention, mean retinal sensitivity (MS) and volumetric analysis 
of the central 30 degrees of the retinal field (V30) in the treated eye were similar to levels observed twenty-four months 
pre-intervention, while the untreated eye showed a continued downward trajectory.  

We also disclosed positive data from the Phase 1/2 clinical trial at the AAO 2022 Annual Meeting in October 

2022.  Treatment with botaretigene sparoparvovec was found to be generally safe and well-tolerated, with no dose-limiting 
events. Adverse events profile was anticipated and manageable, with most adverse events related to the surgical delivery 
procedure, transient and resolved without intervention. A total of three serious adverse events were observed in the overall 
Phase 1/2 clinical study; two serious adverse events, which were previously reported, were observed in the dose-escalation 
phase of the study (n=10; one retinal detachment and one panuveitis in the low dose cohort), and a single additional serious 
adverse event of increased intraocular pressure was observed in the dose escalation phase and resolved with treatment.  
Sustained or increased functional improvements were demonstrated at six months post-treatment in multiple endpoints 
across each of the three domains of vision -- retinal function, visual function, and functional vision --

in patients treated with botaretigene sparoparvovec when compared to the randomized untreated control arm of the study.

We are actively dosing patients in our Phase 3 Lumeos clinical trial, a randomized, controlled study of

botaretigene sparoparvovec for the treatment of XLRP associated with variants in the RPGR gene.

The FDA has granted Fast Track and orphan drug designations to botaretigene sparoparvovec.  Competent 
authorities in the European Union, or EU, have granted Priority Medicines, or PRIME, advanced therapy medicinal 
product, or ATMP, and orphan drug designations to botaretigene sparoparvovec.

AAV-RPE65 for the Treatment of RPE65-Associated Retinal Dystrophy

We are developing AAV-RPE65 for the treatment of retinal dystrophy associated with mutations in the RPE65

gene. RPE65-associated retinal dystrophy causes rod photoreceptor dysfunction and impaired vision from birth.  Absence 
of RPE65 results in severe dysfunction of rods and causes impaired vision in dim lighting conditions.  Although cone 
photoreceptors are generally preserved during childhood in RPE65-deficient patients, the lack of function and degeneration 
of the rods eventually results in the loss of cones and degeneration of the whole retina over time.  Consequently, most
 RPE65-associated retinal dystrophy patients experience central vision loss progressing to complete blindness by early
adulthood.

Based on an estimated prevalence of approximately one in 500,000 people in the United States suffering from

Leber congenital amaurosis, or LCA, related to mutations in the RPE65 gene, and approximately one in 70,000 people in
the United States having RP due to mutations in the RPE65 gene, RPE65-deficiency occurs in approximately one in 
125,000 people in the United States.  There are estimated to be approximately 6,000 RPE65-deficiency patients in the 
United States, Japan and EU5, with almost 30% of those patients being under the age of 30 and approximately 50 new 
cases being diagnosed annually.  We have developed a gene therapy candidate optimized for safety and potency for the 
treatment of RPE65-associated retinal dystrophy, AAV-RPE65. AAV-RPE65 is an AAV2/5 viral vector, in which a codon
optimized RPE65 gene is driven by a novel synthetic retinal pigment epithelium cell specific promoter.

The FDA has approved the first gene treatment for RPE65-associated retinal dystrophy, Luxturna, a commercially 
available product developed by Spark Therapeutics, Inc., which was purchased by Roche.  While RPE65-associated retinal 
dystrophy primarily causes a loss of rod function initially leading to impaired vision in dim light, these patients ultimately 
experience complete blindness because of degeneration of the cone rich fovea.  To prevent blindness, therefore, we believe 
it is critical to treat the central retina in order to maintain structural integrity in this region and save central vision.  We aim 
to treat as extensive an area of the central retina as possible, including the cone rich fovea.  Thus, in addition to improving 
rod function, we aim to provide sufficient RPE65 protein to the cells in the central retina to prevent the degeneration of 
both rods and cones in this region, and thereby prevent the progression to complete blindness.

Clinical Development of AAV-RPE65

We have an ongoing natural history study in patients with RPE65-associated retinal dystrophy with approximately

30 patients enrolled that allows us to collect structural and functional data on prospectively defined endpoints, including
functional tests, retinal imaging, and electrophysiological assessments.

Our Phase 1/2 clinical trial enrolled RPE65-associated retinal dystrophy patients in the UK and U.S.  Dosing in 
the Phase 1/2 clinical trial was completed in June 2018.  The primary endpoint of this open-label, dose-escalation clinical 
trial is safety.  Secondary endpoints include the outcomes of a range of functional tests, detailed structural analysis of the 
retina and quality of life measures. A total of 15 patients were treated in this clinical trial, including nine adult patients in 
three dose escalation cohorts and six pediatric patients in the pediatric extension arm of the trial.

Table of Contents

In May 2019, we announced positive topline safety and efficacy data from the Phase 1/2 trial of AAV-RPE65.

Additional data from this study were presented at the Retina Subspecialty Day of the American Academy of
Ophthalmology Annual Meeting in October 2019.

AAV-RPE65 met the study’s primary endpoint of safety and tolerability. Additionally, AAV-RPE65 demonstrated

statistically significant improvement across several secondary endpoints assessing clinical activity. Significant
improvement in vision was demonstrated at six months after AAV-RPE65 treatment, as measured by assessments of vision-
guided mobility, retinal sensitivity, visual acuity and contrast sensitivity. Larger improvements from baseline in functional
vision were observed between treated and control eyes at lower light levels. We believe these outcomes address the core
functional manifestation of RPE65-associated retinal dystrophy, which typically causes vision impairment beginning in
early childhood that is most pronounced in low-light conditions, and is consistent with the proposed mechanism of action
of AAV-RPE65.

We continue to evaluate the initiation of a Phase 3 clinical trial for AAV-RPE65.

The FDA and European Medicines Agency, or EMA, each granted orphan status to AAV-RPE65 for the treatment
of LCA caused by mutations in the RPE65 gene.  The FDA also granted AAV-RPE65 rare pediatric disease designation for 
the treatment of inherited retinal dystrophy due to biallelic RPE65 mutations.

AAV-CNGB3 and AAV-CNGA3 for the Treatment of Achromatopsia

Achromatopsia, or ACHM, is an IRD that specifically prevents cone photoreceptors from functioning.  ACHM 

patients are legally blind from birth and usually suffer from severely reduced visual acuity of 20/200 or worse, a disabling 
sensitivity to light, or photoaversion, total color blindness and involuntary back and forth eye movements, or nystagmus. 
ACHM patients suffer significant vision loss due to the complete lack of cone function. ACHM occurs in approximately 
one in 30,000 people in the United States.  The CNGB3 and CNGA3 genes are the two most common genes that have been
identified as causing ACHM, together accounting for up to 92% of ACHM cases, with CNGB3 slightly more common than
CNGA3 in most geographic territories.

There are estimated to be approximately 12,000 patients with ACHM caused by mutations in CNGB3 in the 

United States, Japan, and the EU5, with about 25% of those patients being under the age of 18 and approximately 125 new 
cases being diagnosed annually.  We believe the availability of a therapeutic option may increase patient identification and 
the estimated prevalence of ACHM.

ACHM is predominantly a stationary disease, which means that ACHM patients’ retinas contain non-functioning 
cones that survive intact for many decades.  This is in contrast to many IRDs in which the entire retina slowly degenerates 
over a patient’s life.  This extended survival of cones with their potential for light sensitivity presents a wide window of 
opportunity to introduce a normal copy of the mutated gene via a gene therapy product candidate and thereby restore cone 
function. While the stationary nature of ACHM means that cones remain present for decades, the functional connections 
between active cones and the visual cortex in the brain are thought to become fixed in teenage years.  Therefore, we 
believe that younger individuals are likely to benefit most from gene therapy treatment for ACHM because of their greater 
visual plasticity. Another debilitating symptom of ACHM, which lasts throughout life, is photoaversion.  A disabling and 
ubiquitous symptom of ACHM, photoaversion is the avoidance of light due to discomfort in the presence of levels of light 
equivalent to a normally lit room or daylight.  ACHM patients often avoid light and wear dark glasses, which further 
diminishes their already very poor vision.  We believe it is possible that restoration of cone function in adult patients might 
have an impact on photoaversion even if brain plasticity is limited.

We believe that gene therapy treatment for ACHM in which we aim to restore cone function via a gene

replacement strategy may offer benefits across a range of ages, which we aim to define in our clinical development
programs.

10

Table of Contents

We have designed specifically optimized gene therapy viral vector candidates to treat ACHM caused by mutations
in each of CNGB3 and CNGA3, with which we aim to address the majority of patients suffering from ACHM.  Our product 
candidates are delivered via subretinal injection covering the central macula region of the eye, where most of the cones in 
the retina are located.

We have an ongoing natural history study in ACHM including over 90 patients that allows us to collect structural
and functional data for up to five years on prospectively defined endpoints, including functional tests, retinal imaging and
electrophysiological assessments. We believe access to these ACHM patients has enabled us to efficiently enroll the most
appropriate patients into our CNGB3 and CNGA3 Phase 1/2 clinical trials.   In addition to giving us access to patients and 
potentially accelerated enrollment in our treatment studies, we believe the prospective natural history data on each treated 
patient allow us to gather robust data from our Phase 1/2 clinical trials in a condensed timeframe.

Clinical Development of AAV-CNGB3 for the Treatment of ACHM Caused by Mutations in the CNGB3 Gene

We have developed a product candidate, AAV-CNGB3, to treat ACHM caused by mutations in the CNGB3 gene.  
Mutations in the CNGB3 gene prevent cone photoreceptors from functioning because CNGB3’s gene product is integral to 
the formation of a specific membrane channel that enables cones’ electrical response to light.  CNGB3 is a gene exclusively
expressed in cones and our aim is to replace the absent function of the mutant CNGB3 gene with a normal copy of the gene 
in cones of IRD patients and thereby restore cone function.  In order to drive expression of the functional CNGB3 gene
specifically in cones and not in other cells of the retina, we use the cone specific human cone arrestin, or CAR, promoter to
drive the expression of a codon optimized CNGB3 cDNA.  Codon optimization improves protein expression by increasing 
translation efficiency.  To transfect cone photoreceptors, we use the AAV8 capsid, which enables the efficient delivery of 
the CNGB3 gene cargo to those photoreceptors.  As the vast majority of the cones in the eye are located centrally and 
concentrated in the macula, we treat this central region of the retina through subretinal injection to deliver the viral vector 
product candidate to the photoreceptors in which its activity is required.

We have completed enrollment and dosing of the Phase 1/2 clinical trial of AAV-CNGB3 in both adult and

pediatric patients.  In this trial, AAV-CNGB3 was delivered via subretinal injection of up to 0.5mL targeting the central 
region of the retina, including the macula and fovea, where most of the cones are located.  One eye is treated in each 
patient.  The primary endpoint of this open-label, dose-escalation clinical trial is safety. Secondary endpoints include the 
outcomes of a range of functional and structural assessments.

Dosing was completed in this clinical trial in May 2019.  In the dose escalation portion of the trial, we treated 11 
adults. We also treated 12 children in the pediatric expansion cohorts. Six months following treatment, patients can move 
onto a long term follow up study in which they are followed for safety and indication of benefit for an additional four and a 
half years.

Our gene therapy product candidate AAV-CNGB3 was granted orphan drug designation by the FDA and the

European Commission for the treatment of achromatopsia caused by mutations in the CNGB3 gene, rare pediatric disease
designation by the FDA for the treatment of achromatopsia caused by mutations in the CNGB3 gene, and Fast Track
designation by the FDA for the treatment of achromatopsia caused by CNGB3 mutations.  We were granted PRIME 
designation by the EMA in October 2018 based on data from the first adult treatment cohort along with preclinical data.

Clinical Development of AAV-CNGA3 for the Treatment of ACHM Caused by Mutations in the CNGA3 Gene

We are also developing AAV-CNGA3 to treat ACHM caused by mutations in the CNGA3 gene.  We have 
designed a synthetic promoter to drive high levels of CNGA3 expression specifically in cones because we believe a larger
amount of CNGA3 protein is required to restore cone function as compared to CNGB3.  AAV-CNGA3 utilizes this 
proprietary pan cone promoter to drive a codon optimized CNGA3 gene sequence.  We believe this novel promoter can 

11

Table of Contents

drive sufficient expression of CNGA3 in cones to restore light sensitivity to these cones in CNGA3 deficient patients.  We 
use the AAV8 capsid to transfect cone photoreceptors in the back of the eye and we target the cones concentrated in the 
central region of the retina via a subretinal injection that covers the macula.

We have completed enrollment and dosing of the open-label, dose-escalation Phase 1/2 clinical trial of AAV-

CNGA3 in patients with ACHM due to mutations in the CNGA3 gene.

Our gene therapy product candidate AAV-CNGA3 was granted orphan drug designation by the FDA and EMA,

rare pediatric disease designation by the FDA, and in January 2021, was granted Fast Track designation by the FDA for the
treatment of ACHM caused by CNGA3 mutations.

AAV-AIPL1 for the Treatment of LCA4

LCA4 is an IRD that causes complete blindness before age five.  AIPL1 is a central protein for the maintenance of 

photoreceptor structure and function.  Deletion of the AIPL1 gene causes the most severe form of early retinal dystrophy, 
LCA4, in which the retinal structure is destroyed with complete vision loss.  LCA4 is rare, representing approximately 8% 
of all LCA cases.

There are currently no approved treatments for LCA4, and we believe an effective intervention will require

introducing a normal functional copy of the AIPL1 gene into rod and cone photoreceptors early in a patient’s life while 
some retinal structure remains in order to activate function and survival of the photoreceptors that are still present.  We 
believe gene therapy has the potential to be the only effective way to address the disease’s root cause.

LCA4’s extremely rapid progression, rarity and early age of onset make the standard process of seeking regulatory

approval through clinical development challenging because adult safety trials would not yield meaningful data given the
early onset of the disease.

To address LCA4, we developed a viral vector to replace the AIPL1 gene in all photoreceptors by using the AIPL1

cDNA driven by the rhodopsin kinase promoter, which is active in both rods and cones.

We have manufactured and released AAV-AIPL1 for compassionate use under an MHRA specials license in the 

UK to treat LCA4 patients.  A specials license allows physicians to prescribe a treatment of AAV-AIPL1 for LCA4 patients 
they deem appropriate.  We play no role in the physician’s treatment decision.  We intend to use any data produced by the 
compassionate use treatment to inform any potential clinical development plan as well as any interactions with the 
regulatory agencies that would enable us to make this intervention more widely available to the LCA4 patient population.

As the manufacturer of AAV-AIPL1 under a specials license, we have a record retention requirement and a

continuing obligation to inform the MHRA of any suspected adverse reaction to our medicinal product which is a serious
adverse reaction.

The UK’s Human Medicines Regulations 2012 allow for the manufacture and supply of medicinal products not 

authorized for marketing to patients with special needs at the request of the healthcare professional responsible for the 
patient’s care (these products are referred to as “specials”).  A special may only be supplied in: (i) response to an 
unsolicited order from a healthcare professional responsible for the care of the patient, (ii) if the product is manufactured 
and assembled in accordance with the specifications of that healthcare professional to fulfil the special needs of the 
individual patient that cannot be met by products already authorized for marketing and (iii) if the product is manufactured 
under a specials license granted by the MHRA.

Manufacturing a special also imposes a five year record retention requirement subject to review by the MHRA,

including details of any suspected adverse reaction to the product so sold or supplied of which the person is aware or

12

Table of Contents

subsequently becomes aware, as well as a continuing obligation to notify the MHRA of any suspected adverse reaction to
the medicinal product which is a serious adverse reaction.

The FDA and European Commission granted orphan designation to AAV-AIPL1 for treatment of inherited retina

dystrophy due to defects in AIPL1 gene.

Ophthalmology Preclinical Development Pipeline

We also have a preclinical IRD development pipeline focused on diseases caused by mutations in additional 
genes.  In order to expand our gene therapy pipeline for retinal diseases, we are also developing treatments for certain 
multifactorial eye diseases, which are diseases caused by multiple genetic or environmental factors.

AAV-RDH12 for the Treatment of RDH12 Mutation-Associated Retinal Dystrophy

Disease-causing sequence variants in RDH12 cause severe retinal dystrophy most often resulting in the clinical 

diagnosis of Leber congenital amaurosis (LCA) and early onset severe retinal dystrophy (EOSRD); although RDH12 
variants have also been associated with a clinical diagnosis of RP.  Sequence variants in RDH12 account for 3.4%–10.5% 
of LCA/EOSRD. Individuals with RDH12 deficiency exhibit widespread retinal degeneration impacting both rods and 
cones, with early macular involvement. Most people with RDH12–LCA/EOSRD experience marked central visual loss by 
their late teens to twenties.  AAV-RDH12 is an AAV based gene therapy designed to deliver a functional copy of the
 RDH12 gene to the retina of patients with genetically defined RDH12 deficiency.

We received orphan drug designation from the FDA as well as orphan medicinal product designation from the

European Commission for AAV-RDH12 for the treatment of RDH12-associated retinal dystrophy.

  We currently have an ongoing natural history study for patients with RDH12 mutation-associated retinal
dystrophy.  This will allow us to collect structural and functional data for up to five years on prospectively defined
endpoints including functional tests, retinal imaging and electrophysiological assessments. We believe access to these
patients and their data will enable us to efficiently enroll the most appropriate patients into a clinical trial for AAV-RDH12.

Wet and Dry Neovascular Age Related Macular Degeneration (AMD)

We are developing pre-clinical programs relating to neovascular age related macular degeneration, or wet AMD.  

We use a gene therapy product to deliver an antibody targeting the vascular endothelial growth factor receptor 2, or anti-
VEGFR2, with the aim of blocking disease related vascular formation in the eye.

Additionally, we are developing a novel approach to treat advanced dry AMD patients who have lost central 

vision through our innovative “rod-to-cone” technology.  By genetically engineering rods with molecules that will improve 
their speed of response to light, we aim to effectively transform a patch of rod photoreceptors in the outer part of the retina 
to behave more like cone photoreceptors, thus improving vision. There is no currently approved therapy that impacts 
disease progression of dry AMD.  The best available treatment for patients after they lose central vision and acuity is 
support and rehabilitation services to help them better utilize the remaining peripheral part of their retina.

Our Salivary Gland Programs

Our second area of clinical focus is xerostomia, a chronic and debilitating disorder of the salivary glands in which 
saliva production is impaired.  Xerostomia may be caused by a number of different insults to the salivary glands, including 
radiation therapy for head and neck cancer and certain autoimmune diseases.

13

Table of Contents

AAV-hAQP1 for the Treatment of Radiation-Induced Grade 2/3 Xerostomia

Radiation-induced xerostomia, or RIX, is a severe and debilitating long-term side effect of radiation treatment for

head and neck cancer. Chronic RIX results in severe side effects, including difficulty swallowing, or dysphagia, oral
discomfort, malnutrition, oral mucositis, changes in taste, increased oral infections and dental cavities, resulting in a
significant negative impact on patient quality of life. Current treatment options for RIX are few and are of limited benefit.
The sialogogues pilocarpine (approved for RIX) and cevimeline (used off-label) are minimally effective in patients with
grade 2/3 RIX where the gland structure and function have been significantly impaired. No new medications for RIX have
been approved in over 20 years.

Worldwide, there are approximately 650,000 new cases of head and neck cancer diagnosed each year, with 
approximately 54,000 cases in the U.S. alone, making it the fifth most common malignancy.  Approximately 85% of 
patients who receive radiation treatment for head and neck cancer experience reduced saliva production during treatment, 
and approximately 50% of those patients who remain cancer free for two or more years after treatment continue to suffer 
from grade 2 or 3 RIX.  There are approximately 170,000 such patients in the U.S., with approximately 5,000 to 10,000 
new cases each year in the U.S.

Salivary glands are an attractive target organ for gene therapy treatments because they are self-contained, partially

immune protected and easily accessible, allowing for non-invasive delivery of small vector doses.

We are developing AAV-hAQP1 to treat RIX by increasing water conduction in the chronically damaged salivary 

glands by introducing a water conducting channel into the remaining epithelial cells of these damaged glands.  Adequate 
water secretion by surviving epithelial cells has the potential to deliver the protective exocrine proteins produced by 
remaining gland cells into the mouth.

The key to our approach is that, unlike the water conducting acinar cells, the water impermeable duct cells of the 

glands appear to be resilient to infrared radiation exposure.  As a consequence of this relative resilience to radiation 
treatment, salivary glands damaged by radiation treatment tend to contain mostly water impermeable ductal epithelial cells.  
To make these duct cells permeable to water, AAV-hAQP1 introduces the gene for the human aquaporin water channel, or
 hAQP1.  We have demonstrated that this has the potential to convey water permeability and causes ductal cells to generate 
an osmotic gradient, which causes them to secrete fluid into the lumen of the duct.

The proof of concept for this mechanism and its ability to increase the volume of saliva secreted by damaged 

salivary glands was observed in a Phase 1 clinical trial conducted by the NIH in patients with chronic grade 2 or 3 RIX.  
The trial was designed as a short-term dose escalation trial of a gene therapy using adenovirus as the vector to deliver the
 hAQP1 to the remaining epithelial cells in the parotid gland of 11 patients suffering from chronic RIX.  There were no 
reported severe adverse events among the patients treated, two out of three patients in each of the first three cohorts in this 
clinical trial were observed to have objective increases in saliva volume produced by the treated parotid gland, with 
increases in parotid flow ranging from 60% to 540%, and all but one of these patients showed a decrease in symptoms of 
dry mouth as measured by subjective visual analog scales, validated in other forms of xerostomia.  The results of this study 
were published in Proceedings of the National Academy of Sciences in 2012.

We are currently conducting a Phase 1 dose escalation clinical trial of AAV-hAQP1 at the NIH in patients with 

grade 2 or 3 RIX who remain cancer free for at least five years after receiving radiation treatment.  In this trial we are using 
AAV2 to deliver the hAQP1 gene, as we believe AAV2 efficiently transfects the salivary gland cells and does not spread 
beyond the target cells.  The aim of the trial is to determine the safety of inserting hAQP1 locally into the salivary glands of 
RIX patients, as well as to measure changes in salivary flow resulting from the introduction of this channel.  This clinical 
trial is being conducted in conjunction with the National Institute of Dental and Craniofacial Research at the United States 
National Institutes of Health, or the NIH, Dental Clinic.

14

Table of Contents

In the third quarter of 2019, we also initiated an open-label, multi-center Phase 1 dose escalation clinical trial of a 

single administration of our product candidate AAV-hAQP1 to one or both parotid glands in patients with grade 2 or 3 RIX.  
In December 2021, we announced preliminary data from this Phase 1 clinical trial.  The announcement included data from 
seven patients treated in cohorts 1, 2 and 3 of the unilateral dose escalation phase of the clinical trial. Six of the seven 
patients who reached 90 days following treatment reported their symptoms of dry mouth as better following treatment 
pursuant to a validated patient reported assessment of xerostomia symptoms, constituting clinically meaningful 
improvement.  One patient who reported the maximum response evaluable at 12-months had reached the 24-month time 
point and reported the same level of response.  In March 2022, we completed enrollment of the study.  A total of 24 
patients received either unilateral (n=12) or bilateral (n=12) treatment in one of eight escalating dose cohorts of three 
patients each.   

In December 2022, we announced additional positive clinical data from the Phase 1 dose escalation clinical trial 
of AAV-hAQP1.  As of the cutoff date of November 30, 2022, all 12 unilaterally treated participants had undergone their 
12-month assessment, with three having completed their 24-month assessment and one having completed their 36-month 
assessment in the long-term follow-up study. All 12 bilaterally treated participants had undergone their 6-month 
assessment. The investigational gene therapy AAV-hAQP1 has been well tolerated with no dose limiting toxicity or 
treatment-related serious adverse events, and improvements have been seen in validated patient reported assessments of 
xerostomia symptoms and in whole salivary flow rate. All subjects are to be followed for one year post-treatment in the 
present study and for an additional four years in the long-term follow-up study, per FDA guidelines. The study’s primary 
endpoint is safety. Secondary endpoints include change from baseline in patient reported measures of xerostomia 
symptoms as well as whole salivary flow rates. 

Based on the safety and efficacy profile of AAV-hAQP1 in the Phase 1 clinical trial and regulatory precedent, we 

intend to initiate a randomized, double-blind, placebo-controlled Phase 2 study evaluating two active doses of AAV-hAQP1 
for the treatment of grade 2 or 3 RIX in the first half of 2023.  

The FDA granted orphan drug designation to AAV-hAQP1 for the treatment of symptoms of grade 2 and grade 3

late xerostomia from parotid gland hypofunction caused by radiotherapy for cancer of the oral cavity.

AAV-hAQP1 for the Treatment of Sjogren’s Syndrome

The destruction of salivary tissue resulting in chronic xerostomia may also be caused by chronic autoimmune 

disease.  Sjogren’s syndrome is an autoimmune disease in which a patient’s immune system may target the salivary glands.  
Chronic inflammation of the salivary glands results in long term damage and chronic xerostomia in many Sjogren’s 
patients.  Data from preclinical studies in animal models of Sjogren’s syndrome and data from explants of minor salivary 
glands of Sjogren’s patients suggest that Sjogren’s syndrome may also be treatable with our AAV-hAQP1 vector.  
Supported by data from our preclinical studies and our ongoing RIX clinical trials, we are currently conducting IND-
enabling studies of AAV-hAQP1 for xerostomia caused by Sjogren’s syndrome.

Our Neurodegenerative Disease Programs

Neurodegenerative diseases are our third area of focus. Relying on our expertise in viral vector design, delivery,

production and manufacturing, we are aiming to develop and optimize vectors to effectively treat both genetic and sporadic
forms of these diseases.

AAV-GAD for the Treatment of Parkinson’s Disease

Our first target indication is Parkinson’s disease, where we have Phase 2 clinical data from a successful

randomized, double-blind, sham-controlled trial.

15

Table of Contents

Affecting nearly one million Americans and 10 million worldwide, Parkinson’s disease is the second-most 
common neurodegenerative disease after Alzheimer’s disease and is the 14th-leading cause of death in the United States.  It 
is associated with a progressive loss of motor control (e.g., shaking or tremor at rest and lack of facial expression), as well 
as non-motor symptoms (e.g., depression and anxiety).  There is no cure for Parkinson’s disease and 60,000 new cases are 
diagnosed each year in the United States alone.

Our product candidate targeting Parkinson’s disease, AAV-GAD, is designed to deliver the glutamic acid
decarboxylase, or GAD, gene to the subthalamic nucleus in order to increase production of GABA, the primary inhibitory 
neurotransmitter in the human brain.  GAD is the rate-limiting enzyme in the synthesis of GABA, therefore we believe that 
increasing subthalamic nucleus GAD expression through gene therapy has the potential to address the dysregulation of 
motor circuits and improve symptoms in Parkinson’s disease patients without affecting other brain regions, which can be 
responsible for complications of existing therapies.

Clinical Development of AAV-GAD

In a blinded Phase 2 clinical trial of AAV-GAD in patients with medically refractory Parkinson’s disease, 45 

patients were randomized 1:1 to receive either AAV-GAD gene therapy delivered by injection into the subthalamic nucleus 
on both sides of the brain or bilateral sham surgery.  Subjects were followed for one year and all results remained blinded 
until the final treated patient reached the 6-month primary endpoint.  The trial met the primary endpoint, of six-month 
change from baseline in double-blind assessment of off-medication motor scores of the Unified Parkinson’s Disease Rating 
Scale, or UPDRS.  At the six-month endpoint, UPDRS score for the AAV-GAD group decreased by 8.1 points (SD 1.7, 
23.1%; p<0.0001) and by 4.7 points in the sham group (1.5, 12.7%; p=0.003).  The AAV-GAD group showed a 
significantly greater improvement from baseline in UPDRS scores compared with the sham group over the six-month 
course of the study (RMANOVA, p=0.04).  An improvement in complications of medical therapy as measured by the 
UPDRS part 4 was observed in the AAV-GAD group at both six and 12 months.  A significant decline in duration of 
disabling dyskinesia was observed only in the AAV-GAD treated patients.

AAV-GAD was reported to be well-tolerated, with no significant adverse events related to the therapy and no 

speech or cognitive complications observed.  The results of the trial were published in the March 2011 issue of The Lancet
Neurology, the August 2014 issue of the Journal of Clinical Investigation and the April 2017 issue of JCI Insight, building
upon publications of the Phase 1 trial data in The Lancet and the Proceedings of the National Academy of Sciences.  In 
addition, in research published in the November 28, 2018 issue of Science Translational Medicine, fifteen patients treated 
with AAV-GAD gene therapy were observed to have expressed a treatment-related reorganization of functional brain 
connectivity that was related to disease symptom improvement.  These flurodeoxyglucose positron emission tomography 
analyses provided objective biological evidence of improvements in abnormal brain networks associated with Parkinson’s 
disease following AAV-GAD gene therapy.

These results were observed in patients treated in both Phase 1 and Phase 2 studies.  Blinded analyses showed 

significant improvements in abnormal thalamic metabolism, a key node in the movement circuitry, in the AAV-GAD 
treated patients.  This pattern of brain network activity was not seen in untreated hemispheres or patients in the sham arm.  
Furthermore, a specific pattern of brain network activity was identified in those subjects with clinical improvements in the 
sham arm, which was different from the pattern observed in AAV-GAD responders.

We filed an Investigational New Drug application (IND) for AAV-GAD in May 2022, and we are now dosing

patients in an AAV-GAD Phase 1 study with material that has been manufactured with our in-house proprietary
manufacturing process at our cGMP manufacturing facility in London. The objective of the AAV-GAD trial is to evaluate
the safety and tolerability of delivery of AAV-GAD into the subthalamic nuclei of participants with Parkinson’s disease.

Neurodegenerative Disease Preclinical Development Pipeline

In addition to our clinical stage Parkinson’s disease program, we continue to conduct research to develop our

preclinical pipeline of gene therapy product candidates for the treatment of other serious diseases of the central nervous
system, including AAV-UPF1 to address motor neuron death in ALS, and an Alzheimer’s disease program focused on
endosomal trafficking dysfunction. Each of these programs are directed towards the underlying cell biology that may be
driving neurogeneration in these diseases.

ALS

ALS is a devastating, progressive, neurodegenerative disease leading to the loss of motor neurons, which are the 

neurons that control the ability to move, speak, swallow and ultimately to breathe.  The gradual paralysis in ALS invariably 
leads to death.  While 10% of ALS cases are caused by inherited genetic mutations, most ALS occurs sporadically, with no 
known genetic cause.  Mutations in over 20 genes have been identified that cause the inherited ALS cases.  
Characterization of these disease-causing genes have implicated several cellular pathways in the disease, with a prominent 
role emerging for genes involved in the cellular control of RNA.  Many new regulatory roles are being discovered for 
RNA, particularly in neurons.

We have designed a viral vector product candidate, AAV-UPF1, with the aim of increasing UPF1 expression in 
the motor neurons of ALS patients.  In preclinical studies, we observed that administration of AAV-UPF1 reduced motor 
neuron death thought to be driven by the toxic effects of several different genetic causes of ALS including, TDP-43, FUS 
and C9orf72.  Improvements in ALS-like symptoms related to limb strength and mobility in rodent models of ALS have 
also been observed following administration of AAV-UPF1.

We believe that gene therapy using AAV-UPF1 may increase UPF1 levels in cells affected by ALS, and we intend

to deliver our viral vector product candidate to the central nervous system via intrathecal injection, or injection into the
spinal canal.

Alzheimer’s Disease

With the world population aging, Alzheimer’s disease has emerged as an extremely common and costly disease.  

While some treatments that have temporary effects on Alzheimer’s disease symptoms are available, there is currently no 
approved treatment that halts the progression of the disease.

Our Alzheimer’s disease program focuses on the endosomal trafficking pathway.  In preclinical studies, we 

observed that increasing levels of key retromer proteins may reverse endosomal trafficking defects.  We are identifying 
suitable retromer targets for gene augmentation in pre-symptomatic Alzheimer’s patients.

There are several reasons why gene therapy is, in principle, well suited for Alzheimer’s disease and other 
neurodegenerative diseases.  The first relates to the pathophysiology, time course, and anatomical spread of these disorders.  
Neurodegenerative diseases generally begin locally in selectively vulnerable regions with “cell sickness” years before 
rampant cell death and wide-spread anatomical distribution.  To be most effective, we believe interventions should be 
administrated early and will benefit from local delivery.  Even then, however, an intervention must maintain its efficacy for 
years because, unlike other cells in the body, neurons do not typically divide over the course of their life.  We believe AAV-
delivered gene therapy products may have a durable effect.  In the best case scenario, one delivery successfully taken up by 
targeted neurons would be sufficient for years of efficacy.

An important component of our approach is the development and validation of surrogate markers of endosomal 

dysfunction and predictive markers of Alzheimer’s disease.  In particular, several well studied biomarkers linked to 
Alzheimer’s disease, such as amyloid-beta and tau, have also been shown to be biomarkers of endosomal trafficking 
dysfunction in neurons.  Such biomarkers could potentially be used to identify patients with Alzheimer’s disease, as well 

17

as demonstrate potential product efficacy in the absence of Alzheimer’s disease symptoms.  By targeting endosomal 
trafficking dysregulation we aim to address the underlying cause of Alzheimer’s disease as well as other neurodegenerative 
diseases, such as certain forms of Parkinson’s disease.

Our Strengths

In addition to our three core therapeutic areas of focus, our six ongoing clinical development programs, and our 

broad pipeline of preclinical programs, we have core capabilities in viral vector design and optimization, gene therapy 
manufacturing and a potentially transformative gene regulation platform technology that allows precise, dose responsive 
control of gene expression by oral small molecules with dynamic range that can exceed 5000-fold.  Utilizing the following 
key strengths, we aim to develop, commercialize and expand our portfolio of product candidates.

● Deep Expertise in Gene Therapy Development: We believe our expertise in viral vector design,

optimization and process development allows us to efficiently advance gene therapy products candidates
from preclinical development to cGMP manufacturing and clinical development through commercialization.

● Potentially Transformative Gene Regulation Platform Technology: We are developing proprietary 

technology to enable innovative gene therapy treatments whose expression can be turned on and off with an 
easily administered small molecule.  We believe the capacity for temporal control of gene therapy products 
has the potential to transform the gene therapy landscape by opening up new treatment possibilities.

● Manufacturing Capabilities and Capacity: We have a flexible and scalable cGMP manufacturing facility
and production process in London, which we expect can supply our current clinical and preclinical programs
through regulatory approval and, should they be approved, provide sufficient capacity for their commercial
production. We have also expanded our manufacturing capabilities with our second, large scale cGMP viral
vector manufacturing facility and our first cGMP plasmid and DNA production facility in Shannon, Ireland.
Coming online in 2022 and stretching over 150,000 square feet, it is the first commercial-scale gene therapy
manufacturing site in Ireland and is unique in its scale and integrated capabilities. The site contains three
facilities, one built to be flexible and scalable for viral vector production for clinical and commercial supply,
in addition, a facility to manufacture plasmid DNA – the critical starting material for producing gene therapy
products – and thirdly, a QC hub performing advanced biochemical quality control testing for our clinical
and commercial programs.

● Robust and Diverse Clinical and Preclinical Pipeline: Applying our portfolio approach to gene therapy
product development, our initial focus is on treatments for ocular disorders, including IRDs and large
degenerative ocular diseases, as well as salivary gland disorders and neurodegenerative diseases. We have six
programs in clinical development, one program under a compassionate use specials license and a broad
preclinical development pipeline.

● Relationships with Leading Institutions: Our longstanding relationships with leading institutions and

experts provides us with guidance on development strategy and access to potential patients for our clinical
trials.

● Natural History Study Data: We sponsor ongoing prospective long-term natural history studies in IRDs

that facilitate our ability to efficiently enroll our treatment studies, potentially reducing clinical trial timelines
and providing insight into the appropriate endpoints for regulatory approval.

Our Strategy

Our goal is to develop and commercialize innovative gene therapy products to treat serious disorders and broaden 

the scope of indications that may be treatable by our gene therapies.  Our strategy to achieve this goal is to:

● successfully complete clinical development, obtain regulatory approval and commercialize our pipeline of

gene therapy product candidates;

● continue to advance the development of our preclinical pipeline product candidates;

● utilize our viral vector design and optimization capabilities to identify and develop new gene therapies for

serious diseases;

● advance the development of our potentially transformative proprietary technology for regulating the activity

of gene therapy products using small molecules and initiate clinical trials of new regulatable product
candidates; and

● continue to pursue and evaluate further strategic collaborations with additional biotechnology and

pharmaceutical companies to leverage our capabilities, manufacturing capacity and proprietary gene
regulation technology.

Gene Therapy Overview

Gene therapy uses a delivery vehicle, referred to as a vector, to insert a functionally active gene into cells in the 

body.  The gene encodes a therapeutic protein that may block disease pathways or may enhance a deficient pathway.  Gene 
therapy has been studied for over 50 years, with a variety of different viral vectors employed to deliver therapeutic genes.  
Since the first clinical study of therapeutic gene transfer in humans in 1990, thousands of gene therapy studies covering a 
broad range of disease targets have been initiated.  In recent years, the first gene therapies have received regulatory 
approval, including approval by the FDA of Luxturna, marketed by Spark Therapeutics, Inc. which was purchased by 
Roche, for treatment of RPE65-associated retinal dystrophy, and Zolgensma, marketed by AveXis, Inc., a Novartis
company, for the treatment of spinal muscular atrophy, resulting in a growing acceptance of gene therapy technology as a
potentially safe and effective therapeutic approach.

Our current programs use adeno-associated virus, or AAV, as the vector for delivering gene sequences into a 

patient’s cells.  The key components of an AAV vector include: (i) the capsid, or the outer viral protein shell that encloses 
the target DNA, which is responsible for binding to the cell surface and allowing the therapeutic gene that it is carrying to 
enter the cell; (ii) the therapeutic gene, or transgene, that encodes the therapeutic protein; and (iii) the promoter, or the 
DNA sequence that drives the expression of the transgene.  AAV is a good vector for gene therapy delivery because of its 
relative safety and broad applicability.  AAV is less immunogenic, or less prone to causing an immune reaction, than 
previous generations of gene therapy vectors, such as adenoviral vectors and AAV does not readily integrate into the 
genome of the target cell, reducing the potential for oncogenesis, or the induction of cancer.  AAV vectors can transfer a 
therapeutic gene into, or transduce, numerous cell types.  Slight differences in capsid proteins can modulate the efficiency 
with which different capsids deliver genes to different cells, thus allowing different AAV capsids to be selected to most 
effectively target particular cell types.

The therapeutic gene sequence that enters the targeted cell includes both the protein coding region and an 

engineered promoter sequence that is used to drive functional gene expression.  These engineered promoters may be 
designed to drive different levels of gene expression or to limit gene expression to specific cell types.  Additional aspects of 
the transgene sequence may be engineered for optimal gene expression, such as codon usage and synthetic introns, which 
may enhance levels of therapeutic protein expression.

19

Table of Contents

Gene therapy can be used to address monogenic diseases, which result in mutations in a single gene in a patient’s 

genome.  In such cases, the viral vector is used to deliver a normal copy of the gene to the cells that are defective due to the 
lack of the gene function.  The normal gene then drives production of the missing protein and offers a therapeutic benefit in 
patients with the disease.  This gene replacement approach underlies all of our IRD programs.

In addition to replacing a gene that is defective or missing in a monogenic disease, gene therapy can also provide a 
therapeutic impact by adding a particular new gene function to cells and thereby change cell behavior and function in other 
types of diseases.  This is the aim of our salivary gland programs, where our treatment is designed to promote water to flow 
through otherwise impermeable cells in damaged salivary glands and increase saliva flow into the mouth.  Additionally, 
gene therapy may be used to deliver a therapeutic protein that may block a disease pathway or enhance a deficient cellular 
pathway in multifactorial diseases such as wet AMD and neurodegenerative diseases, including ALS and Alzheimer’s 
disease.

Importantly, AAV vectors enable targeting of therapeutic genes to non-dividing cells, in which they are thought to 

remain for the rest of the cell’s life.  This means that a single treatment may offer patients a durable effect and long-term 
benefit.  The specific cells of the eye, salivary gland and the neurons that we target in our current gene therapy programs 
are largely non-dividing cells and preclinical evidence has shown that they can be effectively targeted by the specific AAV 
capsids that we use, enabling us to potentially achieve a durable impact on each of the diseases that we treat.

Our Competitive Advantage in IRDs: Vector Engineering, Natural History Studies and Relationships with Leading
Institutions

IRDs as a class are the most common cause of blindness in the working age population worldwide and a leading 
cause of impaired vision in children in developed countries.  There are approximately 200,000 people in each of the U.S., 
EU and UK affected by IRDs.  However, IRDs may be caused by mutations in over 300 identified genes, and in many 
cases each genetically defined IRD may be a small patient population.  Meaningful clinical trials for these sorts of rare 
indications are especially challenging because they require access to sufficient patients and baseline data on each patient in 
order to secure clear indicators of efficacy as a result of intervention.  We seek to address this problem by sponsoring 
prospectively designed natural history studies in each of the indications that we are treating in our Phase ½ trials.

For each of the natural history studies, baseline assessments are made upon enrollment, with follow up 
assessments at later time points.  A broad range of assessments are used, including functional tests, retinal imaging and 
electrophysiological assessments.  The same assessments used for each natural history study are used in our corresponding 
clinical trial targeting the same indication, allowing us to compare the impact of our product candidates on the progression 
of these diseases on a population, as well as individual patient basis.

We expect the natural history studies will enhance our understanding of disease progression for each indication 
that we are targeting and allow us to identify optimal windows for intervention, provide specific functional and structural 
parameters to quantify treatment effects and define clinical endpoints.  These studies also provide us with a source of 
potential patients for our treatment studies and have facilitated efficient enrollment of these studies.  These patients are not 
only genotyped, but also have up to five years of detailed functional and structural assessment data prior to enrollment into 
an appropriate treatment study.

We also have longstanding active relationships and clinical site agreements with leading institutions in retinal

disorder treatments, including, among others, Moorfields Eye Hospital in London, the University of Michigan Kellogg Eye
Center, Massachusetts Eye and Ear, the Medical College of Wisconsin & Froedtert Hospital and the Casey Eye Institute at
the Oregon Health & Science University.  These institutions and others where we have active relationships are among the 
premier treatment centers for the indications that we are pursuing and provide us with access to potential patients for our 
clinical trials and experts in IRDs who offer strategic guidance and expertise for our development 

20

strategy.  They provide services with respect to our preclinical and clinical studies.  Participants enrolled at the University 
of Michigan Kellogg Eye Center and Massachusetts Eye and Ear Hospital may travel to the Medical College of 
Wisconsin & Froedtert Hospital for adaptive optic assessments.  The Casey Eye Institute at the Oregon Health & Science 
University provides certain reading center and other clinical services with respect to our clinical trials.

Our Gene Regulation Platform

We are developing a potentially transformative technology designed to precisely and specifically control gene 

therapy expression levels via dose-response to orally delivered small molecules.  The aim of this gene regulation platform 
is to transform gene therapy into a generalizable mechanism for the delivery of biologic drugs.  The idea is that the gene 
encoding a particular biologic drug or a therapeutic antibody would be delivered to target cells in the body, but these genes 
would only be activated in the presence of a specific, proprietary small molecule.  The therapeutic protein would be 
manufactured by the body only in the presence of the small molecule so that intermittent production of the therapeutic 
protein would be achieved by dosing with the small molecule drug.

This temporal regulation of gene therapy products by exogenous small molecules has long been a goal of gene 
therapy researchers.  The ability to regulate transgenes by introducing temporal control has the potential to transform the 
gene therapy landscape and the biologics industry as a whole.  Our approach focuses on riboswitches to regulate gene 
expression rather than on the modulation of transcription factor activity.

Riboswitches are pieces of RNA that fold into alternative shapes depending on the binding of a specific small 

molecule to that RNA sequence.  One RNA shape allows the gene containing the riboswitch to be active, while the 
alternative shape inactivates the gene.  Riboswitches are used extensively by bacteria, but none have been identified in 
mammalian cells to date.

We designed de-novo mammalian riboswitches that we have observed respond to small molecules to switch genes
on and off in mammalian cells and in vivo in mice.  Our riboswitch contains a stretch of RNA sequence, called an aptamer, 
that binds to a specific small molecule.  The riboswitch is inserted into the therapeutic transgene cDNA.  In the absence of 
the specific small molecule, the unbound riboswitch folds into the shape that drives the destruction of the RNA message 
and no therapeutic protein is produced in the absence of the small molecule.  However, when the small molecule is present 
and binds to the riboswitch it adopts the alternative RNA shape, causing stable messages to be formed and the therapeutic 
protein to be produced.

One of the features of our mammalian riboswitch is its unprecedented dynamic range of greater than 5,000-fold.  

We believe this technology is viable for a therapeutic product and is also the first instance of a proprietary system for 
screening randomized aptamers and small molecules within mammalian cells for functional interactions.

Using our proprietary technology, we have demonstrated the ability to regulate multiple genes in vitro and in vivo

in multiple tissue types using multiple small molecules.

Our Manufacturing Capabilities

We own and operate a cGMP manufacturing facility situated in London, United Kingdom.  Supporting our global 

approach to clinical development and market supply, we designed the 29,000 square foot facility to meet multiple 
regulatory standards, including the MHRA, EMA and FDA standards.

We believe our facility can supply our current clinical and preclinical programs through regulatory approval and, 
should they be approved, provide sufficient capacity, for commercial production.  Strategically, we believe our facility will 
minimize our dependence on third-party CMOs, which we believe provides a significant strategic, clinical and commercial 
advantage.

21

Table of Contents

Our London facility is flexible and scalable, with eleven independent air handling units, two cell culture suites and 

three separate viral vector production suites, which allows us to produce multiple product candidates in parallel, as well as 
sequentially at different scales.  This allows us to accommodate up to three independent parallel manufacturing streams of 
viral vector products that are isolated within dedicated production areas.

Our London manufacturing facility includes an integrated analytical department and in-house analytical tool kit 

that allows for in-house release of clinical and commercial manufactured products.  It is also equipped with dedicated areas 
for microbiology, molecular biology, and cell-based analytics.  Our analytical department can perform product related 
assays, allowing us to retain and gain expertise that is normally lost to third parties.  The close integration allows for rapid 
turnaround and flexibility in scheduling of key assays, reducing lead times for product candidate releases.  Further, our 
dedicated product fill and finish suite allows us to manufacture a full range of clinical and commercial products under one 
roof and in our control.

We have more than 205 highly trained multidisciplinary staff on our manufacturing team with backgrounds in a
diverse array of manufacturing sciences, technologies, analytics and production working together to expedite delivery of
gene therapy products.

We have identified and licensed a proprietary HEK-293 cell line that is well characterized and that we have 

banked in hundreds of vials.  The specific cell line, size of the bank, culture media, and cryopreservation agents have been 
selected to facilitate bridging between process development platforms and targets.  Our HEK-293 cells are suitable for both 
the adherent culture platform and the bioreactor process.  We believe the ability to use the same cell line throughout the 
product and process development lifecycle will allow us to use a bracketed approach to process validation and 
comparability, which we believe may reduce the time and costs related to their implementation.

We have expanded our manufacturing capabilities with our second, large scale cGMP viral vector manufacturing 

facility and our first cGMP plasmid and DNA production facility in Shannon, Ireland. We completed the acquisitions of the 
buildings and long leasehold interest in January 2021.  The campus encompasses 150,000 square feet and contains three 
facilities, one built to be flexible and scalable for viral vector production for clinical and commercial supply, in addition, a 
facility to manufacture plasmid DNA – the critical starting material for producing gene therapy products – and thirdly, a 
QC hub performing advanced biochemical quality control testing for MeiraGTx clinical and commercial programs.

We believe that building a second viral vector manufacturing facility and bringing cGMP plasmid and DNA 

production, as well as QC analytics, in-house provides greater flexibility and efficiency as we advance our product 
candidates through development, and should they be approved, commercial production.  

Our significant investment in the development of our internal manufacturing capacity and expertise to allow for
better control over our process development timelines, costs, product quality and intellectual property provides us with a
key competitive advantage.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly changing technologies, significant 

competition and a strong emphasis on intellectual property.  This is true in the field of gene therapy generally, and in the 
treatments for our key disease areas.  While we believe that the strength of our team, gene therapy expertise, scientific 
knowledge and intellectual property provide us with competitive advantages, we face competition from several sources, 
including large and small biopharmaceutical companies, academic research institutions, government agencies and public 
and private research institutions.  Not only must we compete with other companies that are focused on gene therapy, but 
any product candidates that we successfully develop and commercialize will compete with existing therapies and new 
therapies that may become available in the future.

22

Table of Contents

Many of our competitors have significantly greater financial resources and expertise in research and development, 

manufacturing, preclinical testing, clinical trials, regulatory approvals and product marketing than we do.  These 
competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing 
clinical trial sites and patient registration for clinical trials and acquiring technologies complementary to, or necessary for, 
clinical programs.  Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more 
resources being concentrated among a smaller number of our competitors.  Smaller or early stage companies may also 
prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

There are other organizations working to improve existing therapies or to develop new therapies for our initially 

selected disease indications.  Depending on how successful these efforts are, it is possible they may increase the barriers to 
adoption and success for our product candidates, if approved.  These efforts include two product candidates Applied 
Genetic Technologies Corporation, or AGTC, have in Phase ½ clinical trials to treat ACHM related to CNGB3 and
CNGA3, respectively, a product candidate in Phase ½ clinical trials by each of 4D Molecular Therapeutics, Inc. and AGTC
to treat XLRP, as well as Luxturna, marketed by Spark Therapeutics, Inc., and has been approved to treat RPE65-
associated retinal dystrophy.  We are not aware of any other gene therapy product candidates in clinical development 
targeting xerostomia.  We are aware of other ALS gene therapies utilizing different treatment mechanisms to treat different 
genetically defined subsets of ALS patients, as well as gene therapy product candidates being developed for the treatment 
of Parkinson’s disease, including those being developed by Voyager Therapeutics, Inc., Prevail Therapeutics, Inc. and 
Axovant Sciences Ltd.

We anticipate that we will face intense and increasing competition as new drugs enter the market and advanced 

technologies become available.  We expect any treatments that we develop and commercialize to compete on the basis of, 
among other things, efficacy, safety, convenience of administration and delivery, price, the level of generic competition and 
the availability of reimbursement from government and other third-party payors.

Intellectual Property

Our success depends in large part upon our ability to secure and maintain proprietary protection for our 
technologies and products and to operate without infringing the proprietary rights of others.  Our policy is to protect our 
proprietary position by, among other methods, filing or collaborating with our licensors to file U.S. and foreign patent 
applications related to our proprietary technology, inventions and improvements that are important to the development and 
implementation of our business.  We also use other forms of protection, such as confidential information and trademark 
protection, particularly where we do not believe patent protection is appropriate or obtainable.  Our patent portfolio 
consists of a combination of issued patents and pending patent applications that are owned or licensed from third parties.

As of December 31, 2022, we own, co-own, have an exclusive license, or an exclusive option to license 297 

United States and foreign issued or allowed patents and 466 patent applications, pending in the United States and 
internationally.  For any individual patent, the term depends on the applicable law in the country in which the patent is 
granted.  In most countries where we have filed patent applications or in-licensed patents and patent applications, patents 
have a term of 20 years from the application filing date or earliest claimed non-provisional priority date.  In the United 
States, the patent term is 20 years but may be shortened if a patent is terminally disclaimed over another patent that expires 
earlier.  The term of a U.S. patent may also be lengthened by a patent term adjustment, in order to address administrative 
delays by the United States Patent and Trademark Office in granting a patent.  In the United States, the term of a patent that 
covers an FDA-approved drug or biologic may be eligible for patent term extension in order to restore the period of a 
patent term lost during the premarket FDA regulatory review process.  The Drug Price Competition and Patent Term 
Restoration Act of 1984, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the natural 
expiration of the patent.  The patent term restoration period is generally equal to the regulatory review period for the 
approved product which period occurs after the date the patent is issued, subject to certain exceptions.  Only one patent 
may be extended for a regulatory review period for any product, and the application 

23

Table of Contents

for the extension must be submitted prior to the expiration of the patent.  In the future, we may decide to apply for 
restoration of patent term for one of our currently owned or licensed patents to extend its current expiration date, depending 
on the expected length of the clinical trials and other factors involved in the filing of the relevant Biologics License 
Application.

License Agreements

License Agreements with UCLB

We previously entered into several license agreements with UCLB, covering the following inherited retinal 
disease programs: (a) ACHM caused by mutations in CNGB3; (b) ACHM caused by mutations in CNGA3; (c) XLRP; and 
(d) RPE65-mediated IRD (together, the “Licensed Gene Therapy Programs”).  The terms of these license agreements were 
set forth in (i) the license agreement, dated February 4, 2015, as amended, between Athena Vision Ltd. and UCLB (the 
“First UCLB License Agreement”); (ii) the license agreements, dated July 29, 2017, as amended, between MeiraGTx UK 
II Limited and UCL Business, Plc (the “Second UCLB License Agreement”); and (iii) the license agreement, dated March 
15, 2018, among MeiraGTx Limited, MeiraGTx UK II Limited and UCL Business Plc (the “Third UCLB License 
Agreement” and, collectively, the “prior UCLB license agreements”).  In January and February 2019, we amended and 
restated the prior UCLB license agreements to establish a new standalone license agreement (each, a “Stand-Alone UCLB 
Agreement”) for each of the Licensed Gene Therapy Programs.  We have removed from each of the Stand-Alone UCLB 
Agreements our obligation to pay UCLB a share of certain sublicensing revenues as was provided under the First UCLB 
License Agreement and have aligned the material terms of the Stand-Alone UCLB Agreements to track those under the 
Third UCLB License Agreement as previously disclosed and a summary of which is set forth below as is now reflected in 
each of the Stand-Alone UCLB Agreements.

26

Table of Contents

Under the terms of the Third UCLB License Agreement, we paid an initial upfront payment of £6,994, and issued 

to UCLB £100,000 of our ordinary shares.  

Under each of the Stand-Alone UCLB Agreements, UCLB granted us an exclusive, worldwide, and sublicensable

license under certain intellectual property rights controlled by UCLB relating to one of the Licensed Gene Therapy
Programs to develop and commercialize licensed products in a relevant field of gene therapy. We must use diligent efforts
to develop and commercialize the licensed products.

Under the terms of each Stand-Alone UCLB Agreement, we are required to pay UCLB sales milestone payments

of up to a total of £39.8 million in the aggregate and an annual management fee of £50 thousand until certain royalty
payments have been paid. Additionally, pursuant to the Stand-Alone UCLB Agreement related to CNGB3, we paid UCLB
an upfront payment of £1.5 million and issued £1.5 million of the Company’s ordinary shares.

Commencing on the first commercial sale of licensed products under each Stand-Alone UCLB Agreement, we
must make low single-digit percentage royalty payments to UCLB on net sales of such products. Our royalty obligations
under each agreement continue on a licensed product-by-licensed product and country-by-country basis until the latest to
occur of the expiration of the last valid claim of a patent claiming such licensed product in such country, the expiration of
any regulatory exclusivity for all licensed products in such country, or the tenth anniversary of first commercial sale of
such licensed product in such country.

Each Stand-Alone UCLB Agreement will remain in effect on a country-by-country basis until the expiration of

the last payment obligation in such country. Each Stand-Alone UCLB Agreement may be terminated: (a) by either party in
the event of the other party’s material breach that remains uncured for 30 days (or for 14 days in the case of breaches
related to payment obligations), (b) by either party for the other party’s insolvency, (c) immediately by UCLB if we are in
persistent breach of the agreement and the parties fail to agree upon a mechanism to remedy such persistent breach (or we
do not comply with such agreed upon mechanism), or (d) immediately by UCLB if we undergo certain change of control
events or if we enter into a sublicense with certain prohibited persons, which may adversely affect UCL’s and/or UCLB’s
reputation. Each Stand-Alone UCLB Agreement may also be terminated or converted to a non-exclusive license by UCLB
upon three months’ notice if we, based on an independent expert determination, fail to use diligent efforts to develop and
commercially exploit licensed products and do not cure such failure within a certain cure period.

License Agreement between BRI-Alzan Inc. and Brandeis

In May 2013, BRI-Alzan Inc., or BRI-Alzan, entered into a license agreement with Brandeis, or the Brandeis 

Agreement.  On December 31, 2015, we entered into an Agreement and Plan of Merger, or the BRI-Alzan Merger 
Agreement, with BRI-Alzan, and the Brandeis Agreement was assigned to us as a result of such merger.  Pursuant to the 
terms of the BRI-Alzan Merger Agreement, we agreed to make cash payments to the sellers of BRI-Alzan upon the 
achievement of certain milestones, subject to an aggregate cap of $4,500,000.  In addition, we agreed to make low single-
digit percentage royalty payments to the sellers of BRI-Alzan on net sales of any product for the therapeutic or 
prophylactic treatment of ALS that is covered by a valid claim of the patent rights licensed under the Brandeis Agreement.  
The BRI-Alzan Merger Agreement includes customary confidentiality, indemnification, non-competition and non-
solicitation provisions.

Pursuant to the Brandeis Agreement, Brandeis granted us an exclusive, worldwide license under certain patent

rights with claims directed to compositions of matter and methods of use relating to our ALS gene therapy program and the
AAV-UPF1 product candidate to develop and commercialize licensed products.

We must use commercially reasonable efforts to develop and commercialize licensed products.  We also acquired 

non-exclusive, worldwide licenses to certain know-how controlled by Brandeis to exploit licensed products.  We are 
required to pay Brandeis developmental and regulatory milestone payments of up to a total of $1.0 million in the aggregate.  
We are also required to pay Brandeis annual license maintenance fees ranging from $15,000 to $100,000 

27

Table of Contents

depending on the development stage of the licensed product.  Commencing on the first commercial sale of licensed 
products, we must make low single-digit percentage royalty payments to Brandeis on net sales of such products.  In 
addition, we must pay Brandeis mid-teen percentages of sublicensing revenues.

The Brandeis Agreement will remain in effect on a country-by-country basis until the earlier of: (a) 1 year after

the date that we, our affiliates or sublicensees last sell any licensed product in such country or (b) until the expiration of the 
last–to-expire of the licensed patent rights in such country.  The Brandeis Agreement may be terminated by Brandeis for 
our insolvency or for our material breach that remains uncured for 60 days (or for 30 days in the case of breaches related to 
payment obligations).  Such material breach may be cured only once in any 12-month period. Brandeis may also terminate 
any license granted under the Brandeis Agreement if we fail to timely achieve certain regulatory milestone events.

Trade Secrets

We also rely on trade secrets, technical know-how and continuing innovation to develop and maintain our 

competitive advantage.  We require inventors who are identified on any company-owned patent applications to assign 
rights to us.  We also rely on confidentiality agreements with our employees, consultants and other advisors to protect our 
proprietary information.  Our policy is to require third parties that receive material confidential information to enter into 
confidentiality agreements with us.

Trademarks

Our trademark MeiraGTx has been registered in the U.S., UK and EU.

Government Regulation and Product Approval

Governmental authorities in the U.S., at the federal, state and local level, and other countries extensively regulate, 
among other things, the research, development, testing, manufacture, labeling, packaging, promotion, storage, advertising, 
distribution, marketing, post-approval monitoring and reporting and export and import of products such as those we are 
developing.  The processes for obtaining regulatory approvals in the United States and in foreign countries and 
jurisdictions, along with subsequent compliance with applicable statutes and regulations and other regulatory authorities, 
are extensive and require the expenditure of substantial time and financial resources.

FDA Approval Process

We expect our product candidates to be regulated as biologics.  Biological products, including gene therapy 

products, are subject to extensive regulation by the FDA under the Federal Food, Drug, and Cosmetic Act, or FDCA, and 
the Public Health Service Act, or PHSA, and other federal, state, local and foreign statutes and regulations.  Both the 
FDCA and the PHSA and their corresponding regulations govern, among other things, the research, development, safety, 
testing, packaging, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-
approval monitoring and reporting, sampling, and import and export of biological products.  

U.S. Biological Products Development Process

Our products must be approved by the FDA through the Biologics License Application, or BLA, process before 

they may be legally marketed in the United States.  The process required by the FDA before a biologic may be marketed in 
the United States generally involves the following:

● completion of extensive nonclinical studies, sometimes referred to as preclinical laboratory tests, and

preclinical studies and applicable requirements for the humane use of laboratory animals and formulation
studies in accordance with applicable regulations, including good laboratory practices, or GLPs;

28

Table of Contents

● submission to the FDA of an IND which must become effective before clinical trials may begin;

● approval by an independent Institutional Review Board, or IRB, or ethics committee at each clinical site

before the trial is commenced;

● performance of adequate and well controlled human clinical trials according to the FDA’s regulations

commonly referred to as good clinical practices, or GCPs, and any additional requirements for the protection
of human research subjects and their health information, to establish the safety and efficacy of the proposed
biological product for its intended use;

● submission to the FDA of a BLA for marketing approval that includes substantive evidence of safety, purity,

potency and efficacy from results of nonclinical testing and clinical trials;

● satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the biological

product is produced to assess compliance with cGMP to assure that the facilities, methods and controls are
adequate to preserve the biological product’s identity, strength, quality and purity;

● potential FDA audit of the nonclinical and clinical study sites that generated the data in support of the BLA;

and

● FDA review and approval, or licensure, of the BLA.

Before testing any biological product candidate, including a gene therapy product, in humans, the product 

candidate enters the preclinical testing stage.  Preclinical tests, also referred to as nonclinical studies, include laboratory 
evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and 
activity of the product candidate.  The conduct of the preclinical tests must comply with federal regulations and 
requirements, including GLPs.  The clinical trial sponsor must submit the results of the preclinical tests, together with 
manufacturing and controls, information about product chemistry, analytical data, any available clinical data or literature 
and a proposed clinical protocol, to the FDA as part of the IND.  Some preclinical testing, such as reproductive toxicity 
tests and carcinogenicity in animals, may continue even after the IND is submitted.  The IND automatically becomes 
effective 30 days after receipt by the FDA, after which human clinical trials may begin unless the FDA places the clinical 
trial on a clinical hold within that 30-day time period.  In such a case, the IND sponsor and the FDA must resolve any 
outstanding concerns before the clinical trial can begin.  The FDA may also impose clinical holds on a biological product 
candidate at any time before or during clinical trials due to safety concerns or non-compliance.  If the FDA imposes a 
clinical hold, trials may not recommence without FDA authorization and then only under terms authorized by the FDA.  

In addition to the IND submission process, sponsors of certain human clinical trials of cells containing 

recombinant or synthetic nucleic acid molecules, including human gene transfer studies, are subject to evaluation and 
assessment by an institutional biosafety committee, or IBC, a local institutional committee that reviews and oversees 
research utilizing recombinant or synthetic nucleic acid molecules at that institution, pursuant to the National Institutes of 
Health’s Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules, or NIH Guidelines.  The 
IBC assesses the safety of the research and identifies any potential risk to the public health or the environment, and such 
review may result in some delay before initiation of a clinical trial.  While the NIH Guidelines are not mandatory unless the 
research in question is being conducted at or sponsored by institutions receiving NIH funding of recombinant or synthetic 
nucleic acid molecule research, many companies and other institutions not otherwise subject to the NIH Guidelines 
voluntarily follow them.

Clinical trials involve the administration of the biological product candidate to healthy volunteers or patients

under the supervision of qualified investigators, generally physicians not employed by or under the study sponsor’s

29

Table of Contents

control.  Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, 
dosing procedures, subject selection and exclusion criteria, the efficacy measurements to be evaluated and the parameters 
to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain adverse 
events should occur.  Each protocol and any amendments to the protocol must be submitted to the FDA as part of the IND.  
Clinical trials must be conducted and monitored in accordance with the FDA’s regulations comprising the GCP 
requirements, including the requirement that all research subjects provide informed consent.  Further, each clinical trial 
must be reviewed and approved by an independent institutional review board, or IRB, at or servicing each institution at 
which the clinical trial will be conducted.  An IRB is charged with protecting the welfare and rights of study participants 
and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are 
reasonable in relation to anticipated benefits.  The IRB also approves the form and content of the informed consent that 
must be signed by each clinical trial subject or his or her legal representative and must monitor the clinical trial until 
completed.  

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

● Phase 1.  The biological product candidate is initially introduced into healthy human subjects and tested for 
safety.  In the case of some products for severe or life-threatening diseases, especially when the product may 
be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often 
conducted in patients.

● Phase 2.  The biological product candidate is evaluated in a limited patient population to identify possible 
adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted 
diseases and to determine dosage tolerance, optimal dosage and dosing schedule.

● Phase 3.  Clinical trials are undertaken to further evaluate dosage, clinical efficacy, potency, and safety in an 
expanded patient population at geographically dispersed clinical trial sites.  These clinical trials are intended 
to establish the overall risk/benefit ratio of the product and provide an adequate basis for product labeling.

In most cases, the FDA requires two adequate and well controlled Phase 3 clinical trials to demonstrate the safety 

and efficacy of a biological product. In some instances, a single Phase 3 trial, together with other confirmatory evidence 
may be sufficient to support a BLA submission.  Post-approval clinical trials, sometimes referred to as Phase 4 clinical 
trials, may be conducted after initial marketing approval.  These clinical trials are used to gain additional experience from 
the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.  The FDA 
recommends that sponsors observe subjects for potential gene therapy-related delayed adverse events for a 15-year period, 
including a minimum of five years of annual examinations followed by ten years of annual queries, either in person or by 
questionnaire.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all 

clinical activities, clinical data, and clinical trial investigators.  Annual progress reports detailing the results of the clinical 
trials must be submitted to the FDA.  Written IND safety reports must be promptly submitted to the FDA, the NIH and the 
investigators for serious and unexpected adverse events, any findings from other trials, tests in laboratory animals or in
vitro testing that suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious 
suspected adverse reaction over that listed in the protocol or investigator brochure.  The sponsor must submit an IND safety 
report within 15 calendar days after the sponsor determines that the information qualifies for reporting.  The sponsor also 
must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after 
the sponsor’s initial receipt of the information.  Phase 1, Phase 2 and Phase 3 clinical trials may not be completed 
successfully within any specified period, if at all.  The FDA or the sponsor or its data safety monitoring board may suspend 
or permanently discontinue a clinical trial at any time on various grounds, including a finding that the research subjects or 
patients are being exposed to an unacceptable health risk or the clinical trial is not being conducted in accordance with 
FDA regulations.  Similarly, an IRB can suspend or terminate approval of a clinical 

30

Table of Contents

study at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the 
biological product candidate has been associated with unexpected serious harm to patients.  The FDA and the IRB may 
also halt, terminate or impose other conditions if either believes the patients are subject to unacceptable risk.

There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results 
to public registries.  Sponsors of clinical trials of FDA-regulated products, including biologics, are required to register and 
disclose certain clinical trial information, which is publicly available at www.clinicaltrials.gov. Information related to the 
product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is 
then made public as part of the registration.  Sponsors are also obligated to discuss the results of their clinical trials after 
completion.  Disclosure of the results of these trials can be delayed until the new product or new indication being studied 
has been approved.

Concurrent with clinical trials, companies usually complete additional animal trials and must also develop 
additional information about the physical characteristics of the biological product candidate as well as finalize a process for 
manufacturing the product in commercial quantities in accordance with cGMP requirements.  To help reduce the risk of the 
introduction of adventitious agents with use of biological products, the PHSA emphasizes the importance of manufacturing 
control for products whose attributes cannot be precisely defined.  The manufacturing process must be capable of 
consistently producing quality batches of the product candidate and, among other things, the sponsor must develop 
methods for testing the identity, strength, quality, potency and purity of the final biological product.  Additionally, 
appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the 
biological product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

After the completion of clinical trials of a biological product candidate, FDA approval of a BLA must be obtained 

before commercial marketing and distribution of the biological product.  The BLA must include results of product 
development, laboratory and animal trials, human trials, information on the manufacture, pharmacology, chemistry and 
controls of the product, proposed labeling and other relevant information.  In addition, under the Pediatric Research Equity 
Act, or PREA, a BLA or supplement to a BLA must contain data to assess the safety and effectiveness of the biological 
product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and 
administration for each pediatric subpopulation for which the product is safe and effective.

A sponsor who is planning to submit a marketing application for a drug or biological product that includes a new 

active ingredient, new indication, new dosage form, new dosing regimen or new route of administration must submit an 
initial Pediatric Study Plan, or PSP, within sixty days after an end-of-Phase 2 meeting or as may be agreed between the 
sponsor and FDA.  The initial PSP must include, among other things, an outline of the pediatric study or studies that the 
sponsor plans to conduct, including to the extent practicable study objectives and design, age groups, relevant endpoints 
and statistical approach, or a justification for not including such detailed information, and any request for a deferral of 
pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with 
supporting information, along with any other information specified in FDA regulations.  The FDA and the sponsor must 
reach agreement on the PSP.  A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the 
pediatric plan need to be considered based on data collected from nonclinical studies, early phase clinical trials, and/or 
other clinical development programs.  The FDA may grant deferrals for submission of data or full or partial waivers.  
Unless otherwise required by regulation, PREA does not apply to any biological product for an indication for which orphan 
designation has been granted. 

Under the Prescription Drug User Fee Act, or PDUFA, as amended, each BLA must be accompanied by a user 

fee.  The FDA adjusts the PDUFA user fees on an annual basis.  PDUFA also imposes an annual program fee for products.  
Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first 
human drug application filed by a small business.  Additionally, no user fees are assessed on BLAs for products designated 
as orphan drugs, unless the product also includes a non-orphan indication.

31

Table of Contents

Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is 

substantially complete before the agency accepts it for filing.  The FDA may refuse to file any BLA that it deems 
incomplete or not properly reviewable at the time of submission and may request additional information.  In this event, the 
BLA must be resubmitted with the additional information.  The resubmitted application is also subject to an initial review 
before the FDA accepts it for filing.  Once the submission is accepted for filing, the FDA begins an in-depth substantive 
review of the BLA.  The FDA’s goal is to complete the review of standard BLAs within ten months after it accepts an 
application for filing, or, if the application qualifies for priority review, six months after the FDA accepts the application 
for filing.  In both standard and priority reviews, the review process is often significantly extended by FDA requests for 
additional information or clarification. 

The FDA reviews the BLA to determine, among other things, whether the proposed product is safe and potent, or 

effective, for its intended use, and has an acceptable purity profile, and whether the product is being manufactured in 
accordance with cGMP requirements to assure and preserve the product’s identity, safety, strength, quality, potency and 
purity.  The FDA may refer applications for novel biological products or biological products that present difficult questions 
of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, 
evaluation and a recommendation as to whether the application should be approved and under what conditions.  The FDA 
is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when 
making decisions.  During the biological product approval process, the FDA also will determine whether a Risk Evaluation 
and Mitigation Strategy, or REMS, is necessary to assure the safe use of the biological product candidate.  If the FDA 
concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA 
without a REMS, if required.

Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured.  The FDA will 
not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP 
requirements and adequate to assure consistent production of the product within required specifications.  Additionally, 
before approving a BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were 
conducted in compliance with IND study requirements and GCP requirements.  To assure cGMP and GCP compliance, an 
applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production, 
and quality control.

Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the BLA 

does not satisfy its regulatory criteria for approval and deny approval.  If the agency decides not to approve the BLA in its 
present form, the FDA will issue a complete response letter that usually describes all of the specific deficiencies in the 
BLA identified by the FDA.  The deficiencies identified may be minor, for example, requiring labeling changes, or major, 
for example, requiring additional clinical trials.  Additionally, the complete response letter may include recommended 
actions that the applicant might take to place the application in a condition for approval.  If a complete response letter is 
issued, the applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the 
application.  If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, 
the FDA will issue an approval letter.  Under the current PDUFA guidelines, the FDA has committed to reviewing such 
resubmissions in two or six months of receipt depending on the type of information included.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may 

entail limitations on the indicated uses for which such product may be marketed.  For example, the FDA may approve the 
BLA with a REMS, to ensure the benefits of the product outweigh its potential risks.  A REMS is a safety strategy to 
manage a known or potential serious risk associated with a medicine and to enable patients to have continued access to 
such medicines by managing their safe use, and could include medication guides, physician communication plans, or 
elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools.  
The FDA also may condition approval on, among other things, changes to proposed labeling or the development of 
adequate controls and specifications.  The requirement for a REMS can materially affect the potential market and 
profitability of the product.

32

Table of Contents

Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing 

requirements is not maintained or if problems occur after the product reaches the marketplace.  Changes to some of the 
conditions established in an approved BLA, including changes in indications, product labeling, manufacturing processes or 
facilities, require submission and FDA approval of a new BLA or BLA supplement before the change can be implemented.  
A BLA supplement for a new indication typically requires clinical data similar to that in the original application, and the 
FDA uses the same procedures and actions in reviewing BLA supplements as it does in reviewing BLAs.  The FDA may 
require one or more Phase 4 post-market studies or surveillance to further assess and monitor the product’s safety and 
effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-
marketing studies.

Orphan Drug Designation

The FDA may grant orphan drug designation to drugs or biologics intended to treat a rare disease or condition that 

affects fewer than 200,000 individuals in the United States, or if it affects more than 200,000 individuals in the United 
States, there is no reasonable expectation that the cost of developing and marketing the drug or biologic for this type of 
disease or condition will be recovered from its sales in the United States.  Orphan drug designation must be requested 
before submitting a BLA.  After the FDA grants orphan product designation, the identity of the therapeutic agent and its 
potential orphan use are disclosed publicly by the FDA.  Orphan drug designation does not convey any advantage in or 
shorten the duration of the regulatory review and approval process.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant 

funding towards clinical trial costs, tax advantages and BLA user-fee waivers.  In addition, if a product receives the first 
FDA approval for the indication for which it has orphan designation, the product is entitled to orphan drug exclusivity, 
which means the FDA may not approve any other application, including a full BLA, to market the same drug or biologic 
for the same disease or condition for a period of seven years, except in limited circumstances, such as a showing of clinical 
superiority over the product with orphan exclusivity or where the manufacturer with orphan exclusivity is unable to assure 
sufficient quantities of the approved orphan-designated product.  Competitors, however, may receive approval of different 
products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a 
different indication for which the orphan product has exclusivity.  Orphan product exclusivity also could block the approval 
of one of our products for seven years if a competitor obtains approval of the same biological product as defined by the 
FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or 
disease.  If a drug or biological product designated as an orphan product receives marketing approval for an indication 
broader than what is designated, it may not be entitled to orphan product exclusivity.  In addition, exclusive marketing 
rights in the United States may be lost if the FDA later determines that the request for designation was materially defective 
or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare 
disease or condition.

Expedited Development and Review Programs

The FDA has a Fast Track program that is intended to expedite or facilitate the process for reviewing new 
biological products that meet certain criteria.  Specifically, new biological products are eligible for Fast Track designation 
if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet 
medical needs for the disease or condition.  Fast Track designation applies to the combination of the product and the 
specific indication for which it is being studied.  The sponsor of a new biologic may request that the FDA designate the 
biologic as a Fast Track product at any time during clinical development of the product.  The FDA must determine if the 
biologic product candidate qualifies for Fast Track designation within 60 days of receipt of the sponsor’s request.  Unique 
to a Fast Track product, the FDA may consider for review sections of the marketing application on a rolling basis before 
the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the 
application, the FDA agrees to accept sections of the application and determines that the schedule is acceptable, and the 
sponsor pays any required user fees upon submission of the first section of the application. In addition, a Fast Track 
designated product is eligible for more frequent meetings with the FDA to discuss 

33

Table of Contents

the biologic product’s development plan and ensure collection of appropriate data needed to support approval, and may 
result in more frequent written communication from the FDA about such things as the design of the proposed clinical trials 
and use of biomarkers.

In addition, the FDA established a Breakthrough Therapy designation which is intended to expedite the 

development and review of products that are intended to treat serious or life-threatening diseases or conditions.  A 
Breakthrough Therapy-designated product candidate is defined as a drug or biologic that is intended, alone or in 
combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition, and 
preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies 
on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical 
development.  The designation includes all of the features of Fast Track designation, as well as more intensive FDA 
interaction and guidance.

Any product submitted to the FDA for marketing, including a product that has received a Fast Track or 
Breakthrough Therapy designation, may be eligible for other types of FDA programs intended to expedite development 
and review, such as priority review and accelerated approval.  An application seeking marketing approval for a biologic 
product is eligible for priority review if the biologic has the potential to provide safe and effective therapy where no 
satisfactory alternative therapy exists or there is potential for a significant improvement in the treatment, diagnosis or 
prevention of a disease compared to marketed products.  The FDA will attempt to direct additional resources to the 
evaluation of an application for a new biological product designated for priority review in an effort to facilitate the review.  
Priority review means the FDA’s goal is to take action on an application within six months (compared to 10 months under 
standard review).

Additionally, a product may be eligible for accelerated approval.  Biological products studied for their safety and 
effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing 
treatments may be eligible for accelerated approval, which means that they may be approved on the basis of adequate and 
well controlled clinical trials establishing that the product has an effect on a surrogate endpoint that is reasonably likely to 
predict a clinical benefit, or on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity or 
mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability 
or lack of alternative treatments.  As a condition of approval, the FDA may require that a sponsor of a biological product 
subject to accelerated approval perform adequate and well-controlled post-marketing Phase 4 clinical trials.  Failure to 
conduct required post-approval trials, or to confirm a clinical benefit during post-marketing trials, will allow the FDA to 
withdraw the approved biologic product from the market on an expedited basis.  In addition, the FDA currently requires as 
a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the 
commercial launch of the product.  Fast Track designation, priority review and accelerated approval do not change the 
standards for approval but may expedite the development or approval process.

Furthermore, as part of its implementation of the 21st Century Cures Act, the FDA established the Regenerative 

Medicine Advanced Therapy, or RMAT, designation, to facilitate an efficient development program for, and expedite 
review of, certain drugs and biological products.  A biological product is eligible for RMAT designation if it qualifies as a 
RMAT, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any 
combination product using such therapies or products, with limited exceptions, and is intended to treat, modify, reverse, or 
cure a serious or life-threatening disease or condition and for which preliminary clinical evidence indicates that the 
biological product has the potential to address unmet medical needs for such a disease or condition.  Like Breakthrough 
Therapy designation, RMAT designation provides potential benefits that include more frequent meetings with FDA to 
discuss the development plan for the product candidate, and eligibility for rolling review and priority review.  Products 
granted RMAT designation may also be eligible for accelerated approval on the basis of a surrogate or intermediate 
endpoint reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from a meaningful number 
of sites, including through expansion to additional sites.  RMAT-designated products that receive accelerated approval may, 
as appropriate, fulfill their post-approval requirements through the submission of clinical 

34

Table of Contents

evidence, clinical trials, patient registries, or other sources of real world evidence (such as electronic health records); 
through the collection of larger confirmatory data sets; or via post-approval monitoring of all patients treated with such 
therapy prior to approval of the therapy.

Fast Track designation, priority review, accelerated approval, Breakthrough Therapy designation and RMAT 

designation do not change the standards for approval but may expedite the development or approval process.  Even if these 
designations are received, the FDA may later decide that a product candidate no longer meets the conditions for 
qualification. 

Post-Approval Requirements

Rigorous and extensive FDA regulation of biological products continues after approval, particularly with respect 

to cGMP requirements.  Manufacturers are required to comply with applicable requirements in the cGMP regulations, 
including quality control and quality assurance and maintenance of records and documentation.  Other post-approval 
requirements applicable to biological products, include reporting of cGMP deviations that may affect the identity, potency, 
purity and overall safety of a distributed product, record-keeping requirements, reporting of adverse effects, reporting 
updated safety and efficacy information, and complying with electronic record and signature requirements.

After a BLA is approved, the product also may be subject to official lot release.  As part of the manufacturing 

process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution.  
If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA 
together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the 
manufacturer’s tests performed on the lot.  The FDA also may perform certain confirmatory tests on lots of some products, 
such as viral vaccines, before releasing the lots for distribution by the manufacturer.  In addition, the FDA conducts 
laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological 
products.

The FDA may require one or more Phase 4 post-market trials or surveillance to further assess and monitor the 
product’s safety and effectiveness after commercialization, and may limit further marketing of the product based on the 
results of these post-marketing studies.  We also must comply with the FDA’s advertising and promotion requirements, 
such as those related to direct-to-consumer advertising, the prohibition on promoting products for uses or in patient 
populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored 
scientific and educational activities, and promotional activities involving the Internet.  Biologics may be marketed only for 
the approved indications and in accordance with the provisions of the approved labeling.

Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements 

may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible 
civil or criminal sanctions.  Failure to comply with the applicable U.S. requirements at any time during the product 
development process, approval process or after approval, may subject an applicant or manufacturer to administrative or 
judicial civil or criminal sanctions and adverse publicity.  FDA sanctions could include refusal to approve pending 
applications, withdrawal of an approval, clinical hold, warning or untitled letters, product recalls, product seizures, total or 
partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective 
advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. 

Biological product manufacturers and other entities involved in the manufacture and distribution of approved 

biological products are required to register their establishments with the FDA and certain state agencies, and are subject to 
periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and 
other laws.  Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and 
quality control to maintain cGMP compliance.  Discovery of problems with a product after approval may result in 

35

Table of Contents

restrictions on a product, manufacturer, or holder of an approved BLA, including withdrawal of the product from the 
market.  In addition, changes to the manufacturing process or facility generally require prior FDA approval before being 
implemented and other types of changes to the approved product, such as adding new indications and additional labeling 
claims, are also subject to further FDA review and approval.

Biosimilars and Exclusivity

The Biologics Price Competition and Innovation Act of 2009, or BPCIA, created an abbreviated approval 
pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological 
product.  Biosimilarity, which requires that there be no clinically meaningful differences between the biological product 
and the reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, 
and a clinical trial or trials.  Interchangeability requires that a product is biosimilar to the reference product and the product 
must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient 
and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be 
alternated or switched after one has been previously administered without increasing safety risks or risks of diminished 
efficacy relative to exclusive use of the reference biologic.  However, complexities associated with the larger, and often 
more complex, structures of biological products, as well as the processes by which such products are manufactured, pose 
significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years 
following the date that the reference product was first licensed by the FDA.  In addition, the approval of a biosimilar 
product may not be made effective by the FDA until 12 years from the date on which the reference product was first 
licensed.  During this 12-year period of exclusivity, another company may still market a competing version of the reference 
product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data 
from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of their product.  The BPCIA 
also created certain exclusivity periods for biosimilars approved as interchangeable products.  

A biological product can also obtain pediatric market exclusivity in the United States.  Pediatric exclusivity, if 

granted, adds six months to existing exclusivity periods and patent terms.  This six-month exclusivity, which runs from the 
end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in 
accordance with an FDA-issued “Written Request” for such a study.

Other Healthcare Laws and Compliance Requirements

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal 

government and by authorities in the states and foreign jurisdictions in which they conduct their business, which may 
constrain the financial arrangements and relationships through which we conduct our research, as well as, sell, market and 
distribute any products for which we obtain marketing approval. Such laws include, without limitation, federal and state 
anti-kickback, fraud and abuse, false claims and transparency laws and regulations regarding drug pricing and payments or 
other transfers of value made to physicians and other licensed healthcare professionals.  If their operations are found to be 
in violation of any of such laws or any other governmental regulations that apply, they may be subject to penalties, 
including, without limitation, administrative, civil and criminal penalties, damages, fines, disgorgement, the curtailment or 
restructuring of operations, exclusion from participation in federal and state healthcare programs, integrity oversight and 
reporting obligations to resolve allegations of non-compliance and imprisonment.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical or biological 

product for which we obtain regulatory approval.  Sales of any product depend, in part, on the extent to which such product 
will be covered by third-party payors, such as federal, state, and foreign government healthcare programs, 

36

Table of Contents

commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-
party payors.  Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a plan-
by-plan basis.  For products administered under the supervision of a physician, obtaining coverage and adequate 
reimbursement may be particularly difficult because of the higher prices often associated with such drugs.  Additionally, 
separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be 
available, which may impact physician utilization.

In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-

containment programs, including price controls, restrictions on coverage and reimbursement and requirements for 
substitution of generic products.  Third party payors are increasingly challenging the prices charged for medical products 
and services, examining the medical necessity and reviewing the cost effectiveness of pharmaceutical or biological 
products, medical devices and medical services, in addition to questioning safety and efficacy.  Adoption of price controls 
and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and 
measures, could further limit sales of any product.  Decreases in third-party reimbursement for any product or a decision by 
a third-party payor not to cover a product could reduce physician usage and patient demand for the product.

Healthcare Reform

The United States and some foreign jurisdictions are considering or have enacted a number of reform proposals to 

change the healthcare system.  There is significant interest in promoting changes in healthcare systems with the stated 
goals of containing healthcare costs, improving quality or expanding access.  In the United States, the pharmaceutical 
industry has been a particular focus of these efforts and has been significantly affected by federal and state legislative 
initiatives, including those designed to limit the pricing, coverage, and reimbursement of pharmaceutical and 
biopharmaceutical products, especially under government-funded health care programs, and increased governmental 
control of drug pricing.

In March 2010, the Patient Protection and Affordable Care Act, or the ACA, was signed into law, which 
substantially changed the way healthcare is financed by both governmental and private insurers in the United States, and 
significantly affected the pharmaceutical industry.  The ACA contained a number of provisions of particular import to the 
pharmaceutical and biotechnology industries, including, but not limited to, those governing enrollment in federal 
healthcare programs, a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate 
Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, and annual fees based on 
pharmaceutical companies’ share of sales to federal health care programs.  

Since its enactment, there have been judicial, Congressional and executive branch challenges to certain aspects of 
the ACA.  On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by
several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision,
President Biden issued an executive order to initiate a special enrollment period for purposes of obtaining health insurance
coverage through the ACA marketplace from February 15, 2021 through August 15, 2021. The executive order also
instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to
healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work
requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through
Medicaid or the ACA.

Other legislative changes have been proposed and adopted since the ACA was enacted, including aggregate

reductions of Medicare payments to providers of 2% per fiscal year, which was temporarily suspended from May 1, 2020
through March 31, 2022, and reduced payments to several types of Medicare providers.  Moreover, there has recently been 
heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which 
has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among 
other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient 
programs, and reform government program reimbursement methodologies for drug products.  At 

37

Table of Contents

the state level, legislatures have increasingly passed legislation and implemented regulations designed to control 
pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain 
product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage 
importation from other countries and bulk purchasing.

Additionally, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina 
Right to Try Act of 2017, or the Right to Try Act, was signed into law.  The law, among other things, provides a federal 
framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical 
trial and that are undergoing investigation for FDA approval.  Under certain circumstances, eligible patients can seek 
treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access 
program.  There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients 
as a result of the Right to Try Act.

U.S. Data Privacy and Security Laws

In the United States, numerous federal and state laws and regulations, including data breach notification laws,

health information privacy and security laws, including the Health Insurance Portability and Accountability Act of 1996, as
amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and regulations
promulgated thereunder, or collectively, HIPAA, and federal and state consumer protection laws and regulations (e.g.,
Section 5 of the Federal Trade Commission Act), that govern the collection, use, disclosure, and protection of health-
related and other personal information could apply to our operations or the operations of our partners. In addition, certain
state laws, such as the California Consumer Privacy Act, or CCPA, and the California Privacy Rights Act, or CPRA,
govern the privacy and security of personal information, including health-related information in certain circumstances,
some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not
have the same effect, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result
in the imposition of significant civil and/or criminal penalties and private litigation. Privacy and security laws, regulations,
and other obligations are constantly evolving, may conflict with each other to make compliance efforts more challenging,
and can result in investigations, proceedings, or actions that lead to significant penalties and restrictions on data processing.

U.S. Foreign Corrupt Practices Act

The U.S. Foreign Corrupt Practices Act of 1977, or FCPA, prohibits U.S. corporations and individuals from 
engaging in certain activities to obtain or retain business or secure any improper advantage, or to influence a person 
working in an official capacity.  It is illegal to pay, offer to pay or authorize the payment of anything of value to any 
employee or official of a foreign government or public international organization, or political party, political party official, 
or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official 
capacity.  The scope of the FCPA also includes employees and officials of state-owned or controlled enterprises, which 
may include healthcare professionals in many countries.  Equivalent laws have been adopted in other foreign countries that 
impose similar obligations.

Government Regulation Outside of the United States

In addition to regulations in the United States, we may be subject to a variety of regulations in other jurisdictions, 

for instance in the UK or EU, governing, among other things, clinical trials, marketing authorizations, post-marketing 
authorization requirements and any commercial sales and distribution of our products.  Because biologically sourced raw 
materials are subject to unique contamination risks, their use may be restricted in some countries. In addition, ethical, 
social and legal concerns about gene therapy, genetic testing, genetic research and gene-editing technology, could result in 
additional regulations restricting or prohibiting the processes we may use.

38

Table of Contents

Whether or not we obtain FDA approval of a product, we must obtain the requisite approvals from regulatory 

authorities in foreign countries prior to the commencement of clinical trials or marketing of the product in those countries.  
The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary 
from country to country.  If we fail to comply with applicable foreign regulatory requirements, we may be subject to, 
among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating 
restrictions and criminal prosecution.

Non-Clinical Studies and Clinical Trials

Similar to the United States, the various phases of non-clinical and clinical research abroad are subject to

significant regulatory controls.

Non-clinical studies are performed to demonstrate the health or environmental safety of new chemical or
biological substances. Non-clinical studies must be conducted in compliance with the principles of GLP, as set forth in EU
Directive 2004/10/EC. In particular, non-clinical studies, both in vitro and in vivo, must be planned, performed, monitored,
recorded, reported and archived in accordance with the GLP principles, which define a set of rules and criteria for a quality
system for the organizational process and the conditions for non-clinical studies. These GLP standards reflect the
Organization for Economic Co-operation and Development requirements.

Clinical trials of medicinal products in the EU must be conducted in accordance with EU and national regulations 

and the International Conference on Harmonization, or ICH, guidelines on GCPs, as well as the applicable regulatory 
requirements and the ethical principles that have their origin in the Declaration of Helsinki.  Additional GCP guidelines 
from the European Commission, focusing in particular on traceability, apply to clinical trials of ATMPs.  If the sponsor of 
the clinical trial is not established within the EU, it must appoint an entity within the EU to act as its legal representative.  
The sponsor must take out a clinical trial insurance policy, and in most EU member states, the sponsor is liable to provide 
‘no fault’ compensation to any study subject injured in the clinical trial.

The regulatory landscape related to clinical trials in the EU has been subject to recent changes. The EU Clinical

Trials Regulation, or CTR, which was adopted in April 2014 and repeals the EU Clinical Trials Directive, became
applicable on January 31, 2022. Unlike directives, the CTR is directly applicable in all EU member states without the need
for member states to further implement it into national law. The CTR notably harmonizes the assessment and supervision
processes for clinical trials throughout the EU via a Clinical Trials Information System, which contains a centralized EU
portal and database.

While the EU Clinical Trials Directive required a separate clinical trial application, or CTA, to be submitted in

each member state in which the clinical trial takes place, to both the competent national health authority and an
independent ethics committee, much like the FDA and IRB respectively, the CTR introduces a centralized process and only
requires the submission of a single application for multi-center trials. The CTR allows sponsors to make a single
submission to both the competent authority and an ethics committee in each member state, leading to a single decision per
member state. The CTA must include, among other things, a copy of the trial protocol and an investigational medicinal
product dossier containing information about the manufacture and quality of the medicinal product under investigation.
The assessment procedure of the CTA has been harmonized as well, including a joint assessment by all member states
concerned, and a separate assessment by each member state with respect to specific requirements related to its own
territory, including ethics rules. Each member state’s decision is communicated to the sponsor via the centralized EU
portal. Once the CTA is approved, clinical study development may proceed.

The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be

governed by the CTR varies. Clinical trials for which an application was submitted (i) prior to January 31, 2022 under the
EU Clinical Trials Directive, or (ii) between January 31, 2022 and January 31, 2023 and for which the sponsor has opted
for the application of the EU Clinical Trials Directive remain governed by the EU Clinical Trials Directive until

39

Table of Contents

January 31, 2025. After this date, all clinical trials (including those which are ongoing) will become subject to the
provisions of the CTR.

Medicines used in clinical trials must be manufactured in accordance with good manufacturing practices, or GMP.

Other national and EU-wide regulatory requirements may also apply.

During the development of a medicinal product, the EMA and national regulators within the EU provide the 

opportunity for dialogue and guidance on the development program.  At the EMA level, this is usually done in the form of 
scientific advice, which is given by the Scientific Advice Working Party of the Committee for Medicinal Products for 
Human Use, or CHMP.  A fee is incurred with each scientific advice procedure.  Advice from the EMA is typically 
provided based on questions concerning, for example, quality (chemistry, manufacturing and controls testing), nonclinical 
testing and clinical trials, and pharmacovigilance plans and risk-management programs.  Advice is not legally binding with 
regard to any future marketing authorization application of the product concerned.

Marketing Authorizations

In the EU, medicinal products can only be placed on the market after obtaining a marketing authorization, or MA. 
To obtain regulatory approval of an investigational chemical or biological product in the EU, we must submit a marketing 
authorization application, or MAA.    The process for doing this depends, among other things, on the nature of the 
medicinal product.

“Centralized MAs” issued by the European Commission, based on the opinion of the EMA, are valid across the 

entire territory of the EU.  The centralized procedure is compulsory for certain types of product candidates, such as: 
(i) medicinal products derived from biotechnology processes, such as genetic engineering, (ii) medicinal products 
containing a new active substance indicated for the treatment of certain diseases, such as HIV/AIDS, cancer, diabetes, 
neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) designated orphan 
medicines and (iv) ATMPs, such as gene therapy, somatic cell therapy or tissue-engineered medicines.  The centralized 
procedure is optional for product candidates containing a new active substance not yet authorized in the EU, or for product 
candidates that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public 
health in the EU.

The Committee for Advanced Therapies, or CAT, is responsible in conjunction with the CHMP for the evaluation 

of advanced therapy medicinal products, or ATMPs.  The CAT is primarily responsible for the scientific evaluation of 
ATMPs and prepares a draft opinion on the quality, safety and efficacy of each ATMP for which an MAA is submitted.  
The CAT’s opinion is then taken into account by the CHMP when giving its final recommendation regarding the 
authorization of a product in view of the balance of benefits and risks identified.  Although the CAT’s draft opinion is 
submitted to the CHMP for final approval, the CHMP may depart from the draft opinion, if it provides detailed scientific 
justification.  The CHMP and CAT are also responsible for providing guidelines on ATMPs and have published numerous 
guidelines, including specific guidelines on gene therapies and cell therapies.  These guidelines provide additional 
guidance on the factors that the EMA will consider in relation to the development and evaluation of ATMPs and include, 
among other things, the preclinical studies required to characterize ATMPs; the manufacturing and control information that 
should be submitted in an MAA; and post-approval measures required to monitor patients and evaluate the long term 
efficacy and potential adverse reactions of ATMPs.  Although these guidelines are not legally binding, we believe that our 
compliance with them is likely necessary to gain and maintain approval for any of our product candidates.

Under the centralized procedure, the maximum timeframe for the evaluation of an MAA by the EMA is 210 days.  

This excludes so-called clock stops, during which additional written or oral information is to be provided by the applicant 
in response to questions asked by the CHMP.  At the end of the review period, the CHMP provides an opinion to the 
European Commission.  If this opinion is favorable, the Commission may then adopt a decision to grant an MA.

40

Table of Contents

  “National MAs” are issued by the competent authorities of the EU member states, only cover their respective 

territory, and are available for product candidates not falling within the mandatory scope of the centralized procedure. 
Where a product has already been authorized for marketing in an EU member state, this national MA can be recognized in 
another member state through the mutual recognition procedure. If the product has not received a national MA in any 
member state at the time of application, it can be approved simultaneously in various member states through the 
decentralized procedure. Under the decentralized procedure an identical dossier is submitted to the competent authorities of 
each of the member states in which the MA is sought, one of which is selected by the applicant as the reference member 
state.

MAs have an initial duration of five years. After these five years, the authorization may be renewed on the basis
of a reevaluation of the risk-benefit balance. Once renewed, the MA is valid for an unlimited period unless the European
Commission or the national competent authority decides, on justified grounds relating to pharmacovigilance, to proceed
with one additional five-year renewal

In exceptional cases, the CHMP might perform an accelerated review of an MAA in no more than 150 days (not 

including clock stops).  Innovative products that target an unmet medical need and are expected to be of major public 
health interest may be eligible for a number of expedited development and review programs, such as the PRIME scheme, 
which provides incentives similar to the Breakthrough Therapy designation in the U.S.  PRIME is a voluntary scheme 
aimed at enhancing the EMA’s support for the development of medicines that target unmet medical needs.  It is based on 
increased interaction and early dialogue with companies developing promising medicines, to optimize their product 
development plans and speed up their evaluation to help them reach patients earlier.  Product developers that benefit from 
PRIME designation can expect to be eligible for accelerated assessment but this is not guaranteed.  Many benefits accrue to 
sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory 
dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and 
accelerated MAA assessment once a dossier has been submitted. Importantly, a dedicated contact and rapporteur from the 
CHMP is appointed early in the PRIME scheme facilitating increased understanding of the product at EMA’s committee 
level. An initial meeting initiates these relationships and includes a team of multidisciplinary experts at the EMA to 
provide guidance on the overall development and regulatory strategies.

Moreover, in the EU, the European Commission may grant a so-called “conditional MA” prior to obtaining the 

comprehensive clinical data required for an application for a full MA.  Such conditional MAs may be granted for product 
candidates (including medicines designated as orphan medicinal products), if (i) the risk-benefit balance of the product 
candidate is positive, (ii) it is likely that the applicant will be in a position to provide the required comprehensive clinical 
trial data, (iii) the product fulfills an unmet medical need and (iv) the benefit to public health of the immediate availability 
on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data are still 
required.  A conditional MA may contain specific obligations to be fulfilled by the MA holder, including obligations with 
respect to the completion of ongoing or new studies, and with respect to the collection of pharmacovigilance data.  
Conditional MAs are valid for one year, and may be renewed annually, if the risk-benefit balance remains positive, and 
after an assessment of the need for additional or modified conditions and/or specific obligations.  The MA can be converted 
into a standard MA once the MA holder fulfils the obligations that were imposed and the complete data confirm that the 
medicine’s benefits continue to outweigh its risks. The timelines for the centralized procedure described above also apply 
with respect to the review by the CHMP of applications for a conditional MA.

The European Commission may also grant a so-called “marketing authorization under exceptional circumstances”.  

Such MA is intended for products for which the applicant can demonstrate that it is unable to provide comprehensive data 
on the efficacy and safety under normal conditions of use even after the product has been authorized, because the 
indications for which the product in question is intended are encountered so rarely that the applicant cannot reasonably be 
expected to provide comprehensive evidence, or in the present state of scientific knowledge, comprehensive information 
cannot be provided, or it would be contrary to generally accepted principles of 

41

Table of Contents

medical ethics to collect such information.  Consequently, MAs under exceptional circumstances may be granted subject to 
certain specific obligations, which may include the following:

● the applicant must complete an identified program of studies within a time period specified by the competent

authority, the results of which form the basis of a reassessment of the benefit/risk profile;

● the medicinal product in question may be supplied on medical prescription only and may in certain cases be

administered only under strict medical supervision, possibly in a hospital and in the case of a radio-
pharmaceutical, by an authorized person; and

● the package leaflet and any medical information must draw the attention of the medical practitioner to the
fact that the particulars available concerning the medicinal product in question are as yet inadequate in
certain specified respects.

An MA under exceptional circumstances is subject to annual review to reassess the risk-benefit balance in an 
annual reassessment procedure.  Continuation of the authorization is linked to the annual reassessment and a negative 
assessment could potentially result in the MA being suspended or revoked.  The renewal of an MA of a medicinal product 
under exceptional circumstances, however, follows the same rules as a “normal” MA.  Thus, an MA under exceptional 
circumstances is granted for an initial five years, after which the authorization will become valid indefinitely, unless the 
EMA decides that safety grounds merit one additional five-year renewal.  An MA under exceptional circumstances should 
not be granted when a conditional MA is more appropriate.

The EU medicines rules expressly permit the EU member states to adopt national legislation prohibiting or 

restricting the sale, supply or use of any medicinal product containing, consisting of or derived from a specific type of 
human or animal cell, such as embryonic stem cells.  While the products we have in development do not make use of 
embryonic stem cells, it is possible that the national laws in certain EU member states may prohibit or restrict us from 
commercializing our products, even if they have been granted an MA.

Data and Marketing Exclusivity

The EU also provides opportunities for market exclusivity.  Upon receiving MA, reference products generally 

receive eight years of data exclusivity and an additional two years of market exclusivity.  If granted, data exclusivity 
prevents generic or biosimilar applicants from relying on the preclinical and clinical trial data contained in the dossier of 
the reference product when applying for a generic or biosimilar MA in the EU during a period of eight years from the date 
on which the reference product was first authorized in the EU.  The market exclusivity period prevents a successful generic 
or biosimilar applicant from commercializing its product in the EU until ten years have elapsed from the initial MA of the 
reference product in the EU.  The overall ten-year market exclusivity period may be extended to a maximum of eleven 
years if during the first eight years of those ten years, the MA holder obtains an authorization for one or more new 
therapeutic indications with significant clinical benefit over existing therapies. However, there is no guarantee that a 
product will be considered by the EU regulatory authorities to be a new chemical or biological entity, and products may not 
qualify for data exclusivity.

There is a special regime for biosimilars, or biological medicinal products that are similar to a reference medicinal 

product but that do not meet the definition of a generic medicinal product, for example, because of differences in raw 
materials or manufacturing processes.  For such products, the results of appropriate preclinical or clinical trials must be 
provided, and guidelines from the EMA detail the type of quantity of supplementary data to be provided for different types 
of biological product.  There are no such guidelines for complex biological products, such as gene or cell therapy medicinal 
products, and so it is unlikely that biosimilars of those products will currently be approved in the EU.  However, guidance 
from the EMA states that they will be considered in the future in light of the scientific knowledge and regulatory 
experience gained at the time.

Orphan Medicinal Products

The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in the United 
States.  A medicinal product may be designated as orphan if (1) it is intended for the diagnosis, prevention or treatment of a 
life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in 10,000 
persons in the EU when the application is made, or (b) the product, without the benefits derived from orphan status, would 
not generate sufficient return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, 
prevention or treatment of such condition authorized for marketing in the EU, or if such a method exists, the product will 
be of significant benefit to those affected by the condition.  

Orphan drug designation entitles a party to incentives such as reduction of fees or fee waivers, protocol assistance, 

and access to the centralized MA procedure.  The application for orphan drug designation must be submitted before the 
MAA.  The applicant will receive a fee reduction for the MAA if the orphan drug designation has been granted, but not if 
the designation is still pending at the time the MA is submitted.  Upon grant of an MA and assuming the requirement for 
orphan designation are also met at the time the MA is granted, orphan medicinal products are entitled to a ten-year period 
of market exclusivity for the approved therapeutic indication, which means that regulatory authorities cannot accept 
another MA or grant an MA or accept an application to extend an existing MA in respect of a similar medicinal product for 
the same indication for a period of ten years. The period of market exclusivity is extended by two years for orphan 
medicinal products that have also complied with an agreed pediatric investigation plan, or PIP.  Orphan drug designation 
does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The ten-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the 

product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to 
justify maintenance of market exclusivity or where the prevalence of the condition has increased above the orphan 
designation threshold.  Additionally, an MA may be granted to a similar product for the same indication at any time if (1) 
the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior, 
(2) the applicant consents to a second orphan medicinal product application; or (3) the applicant cannot supply enough 
orphan medicinal product.

Pediatric Development

In the EU, MAAs for new medicinal products have to include the results of trials conducted in the pediatric 

population, in compliance with a PIP agreed with the EMA’s Pediatric Committee, or PDCO.  The PIP sets out the timing 
and measures proposed to generate data to support a pediatric indication of the drug for which an MA is being sought.  The 
PDCO can grant a deferral of the obligation to implement some or all of the measures of the PIP until there are sufficient 
data to demonstrate the efficacy and safety of the product in adults.  Further, the obligation to provide pediatric clinical trial 
data can be waived by the PDCO when these data are not needed or appropriate because the product is likely to be 
ineffective or unsafe in children, the disease or condition for which the product is intended occurs only in adult 
populations, or when the product does not represent a significant therapeutic benefit over existing treatments for pediatric 
patients.  Once the MA is obtained in all EU member states and study results are included in the product information, even 
when negative, the product is eligible for a six-months supplementary protection certificate extension (if any is in effect at
the time of approval) or, in the case of orphan medicinal products, a two year extension of the orphan market exclusivity is
granted.

Post-Approval Requirements

Similar to the United States, both MA holders and manufacturers of medicinal products are subject to 

comprehensive regulatory oversight by the EMA, the European Commission and/or the competent regulatory authorities of 
the member states. The holder of an MA must establish and maintain a pharmacovigilance system and appoint an 
individual qualified person for pharmacovigilance who is responsible for oversight of that system.  Key obligations 

43

Table of Contents

include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, or 
PSURs.

All new MAAs must include a risk management plan, or RMP, describing the risk management system that the 
company will put in place and documenting measures to prevent or minimize the risks associated with the product.  The 
regulatory authorities may also impose specific obligations as a condition of the MA.  Such risk-minimization measures or 
post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or the 
conduct of additional clinical trials or post-authorization safety studies.  

The advertising and promotion of medicinal products is also subject to laws concerning promotion of medicinal 

products, interactions with physicians, misleading and comparative advertising and unfair commercial practices. All 
advertising and promotional activities for the product must be consistent with the approved summary of product 
characteristics, and therefore all off-label promotion is prohibited.  Direct-to-consumer advertising of prescription 
medicines is also prohibited in the EU.  Although general requirements for advertising and promotion of medicinal 
products are established under EU directives, the details are governed by regulations in each member state and can differ 
from one country to another.

Failure to comply with EU and member state laws that apply to the conduct of clinical trials, manufacturing
approval, MA of medicinal products and marketing of such products, both before and after grant of the MA, manufacturing
of pharmaceutical products, statutory health insurance, bribery and anti-corruption or with other applicable regulatory
requirements may result in administrative, civil or criminal penalties. These penalties could include delays or refusal to
authorize the conduct of clinical trials or to grant MA, product withdrawals and recalls, product seizures, suspension,
withdrawal or variation of the MA, total or partial suspension of production, distribution, manufacturing or clinical trials,
operating restrictions, injunctions, suspension of licenses, fines and criminal penalties.

The aforementioned EU rules are generally applicable in the European Economic Area, or EEA, which consists of

the 27 EU member states plus Iceland, Liechtenstein and Norway.

Pricing and Reimbursement

Even if a medicinal product obtains an MA in the EU, there can be no assurance that reimbursement for such 

product will be secured on a timely basis or at all.  Governments influence the price of medicinal products through their 
pricing and reimbursement rules and control of national healthcare systems that fund a large part of the cost of those 
products to consumers.  Member states are free to restrict the range of pharmaceutical products for which their national 
health insurance systems provide reimbursement, and to control the prices and reimbursement levels of pharmaceutical 
products for human use. Some jurisdictions operate positive and negative list systems under which products may only be 
marketed once a reimbursement price has been agreed to by the government.  Member states may approve a specific price 
or level of reimbursement for the pharmaceutical product, or alternatively adopt a system of direct or indirect controls on 
the profitability of the company responsible for placing the pharmaceutical product on the market, including volume-based 
arrangements, caps and reference pricing mechanisms.  To obtain reimbursement or pricing approval, some of these 
countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate 
to currently available therapies.  Other EU member states allow companies to fix their own prices for medicines, but 
monitor and control company profits.  The downward pressure on healthcare costs in general, particularly prescription 
medicines, has become very intense.  As a result, increasingly high barriers are being erected to the entry of new products. 
In addition, in some countries, cross border imports from low-priced markets exert a commercial pressure on pricing within 
a country.

Brexit and the Regulatory Framework in the United Kingdom

The UK formally left the EU on January 31, 2020, commonly referred to as “Brexit”. Since the end of the Brexit

transition period on January 1, 2021, Great Britain (England, Scotland and Wales) has not been directly subject to

44

Table of Contents

EU laws, however under the terms of the Protocol on Ireland and Northern Ireland, EU laws have generally applied to
Northern Ireland. On February 27, 2023, the UK Government and the European Commission reached a political agreement
on the “Windsor Agreement” which may revise the Protocol on Ireland and Northern Ireland in order to address some of
the perceived shortcomings in its operation. Under the proposed changes, Northern Ireland would be reintegrated under the
regulatory authority of the MHRA with respect to medicinal products. These proposed changes need to be codified and
agreed by the respective parliaments of the UK and EU before taking effect.

UK Clinical Trials

It is currently unclear to what extent the UK will seek to align its regulations with the EU.  The UK regulatory

framework in relation to clinical trials is derived from existing EU legislation (as implemented into UK law, through
secondary legislation), and after Brexit, EU laws on clinical trials (including the CTR) are no longer directly applicable in
Great Britain (i.e., the UK excluding Northern Ireland). On January 17, 2022, the MHRA launched an eight-week
consultation on reframing the UK legislation for clinical trials. The consultation closed on March 14, 2022 and aims to
streamline clinical trials approvals, enable innovation, enhance clinical trials transparency, enable greater risk
proportionality, and promote patient and public involvement in clinical trials. The outcome of the consultation is being
closely watched and will determine whether the UK chooses to align with the CTR or diverge from it to maintain
regulatory flexibility.  Under the terms of the Protocol on Ireland and Northern Ireland, provisions of the CTR which relate 
to the manufacture and import of investigational medicinal products and auxiliary medicinal products currently apply in 
Northern Ireland. On February 27, 2023, the UK Government and the European Commission reached a political agreement 
on the “Windsor Agreement” which may revise the Protocol on Ireland and Northern Ireland in order to address some of 
the perceived shortcomings in its operation. If implemented, this may have further impact on the application of the CTR in 
Northern Ireland.

UK Marketing Authorizations

The MHRA is now the UK’s standalone regulator for MAAs. All existing centralized procedure MAs were

automatically converted into UK MAs effective in Great Britain and issued with a UK MA number on January 1, 2021
(unless MA holders opted out of this scheme by January 21, 2021). As a result of the implementation of the Protocol on
Ireland and Northern Ireland, centralized procedure MAs remain valid for marketing products in Northern Ireland. Pending
applications which were submitted to EMA prior to the end of the transition period will either be determined in parallel by
the MHRA, or will be put “on hold” until the CHMP issues a positive decision which can be relied upon by the MHRA.
Converted EU MAs will be treated as if they were granted on the date the corresponding centralized procedure MA was
granted and the renewal date will stay the same. If renewals were submitted and no decision was rendered before January
1, 2021, the MHRA will ensure the renewal process is concluded and processed appropriately, and there will be no need to
resubmit the application. From January 1, 2021 the requirements for renewal submissions remain the same as required by
the EMA and the MA holders should continue to submit renewal applications to the MHRA nine months before they expire
(or six months in relation to conditional MAs).

Following January 1, 2021, an applicant for a centralized procedure MA must be established in the EU. After this
date, companies established in the UK can no longer use the centralized procedure and instead must follow one of the UK
national authorization procedures or one of the remaining post-Brexit international cooperation procedures (such as the
Access Consortium) to obtain an MA to market products in the UK. In addition, for a two-year period from January 1,
2021, MHRA may rely on a decision taken by the European Commission on the approval of a new centralized procedure
MA when determining an application for a Great Britain MA; or use the MHRA’s decentralized or mutual recognition
procedures which enable MAs approved in EU member states (or Iceland, Liechtenstein, Norway) to be granted in Great
Britain. Additionally, the ‘Unfettered Access Procedure’ enables MA holders in Northern Ireland to seek recognition in
Great Britain. Post Brexit, the MHRA has updated various aspects of the regulatory regime for medicines in the UK,
including: introducing the Innovative Licensing and Access Procedure to accelerate the time to market and facilitate patient
access for innovative medicines; updates to the UK national approval procedure,

45

Table of Contents

introducing a 150-day objective for assessing applications for MAs in the UK, Great Britain and Northern Ireland and a
rolling review process for MA applications (rather than a consolidated full dossier submission).

UK Orphan Designation

Post-Brexit, the UK has retained the EU Regulation which governs the designation of medicinal products as

orphan medicinal products and which establishes incentives thereto (Regulation (EC) No. 141/2000) as part of UK law by
virtue of the EU (Withdrawal) Act 2018. However under the Retained EU Law (Revocation and Reform) Bill, which is
currently before the UK Parliament, unless this legislation is expressly preserved and “assimilated” into domestic law or
extended by ministerial regulations (to no later than June 23, 2026) it will automatically expire and be revoked by
December 31, 2023. There is therefore uncertainty about the future regulations relating to orphan designation in Great
Britain, and any future changes to the legal requirements could lead to greater regulatory complexity and increased costs to
our business.

The MHRA is responsible for reviewing applications from companies for orphan designation at the time of a
MAA. If a medicinal product has been designated orphan in the EU under Regulation (EC) 141/2000, a Great Britain
orphan MAA can be made under regulation 50G of the Human Medicines Regulation 2012 (as amended). A UK-wide
orphan MAA can only be considered in the absence of an active EU orphan designation.

If a UK-wide orphan MA is granted and the medicinal product subsequently receives EU orphan designation, the

MA holder would need to submit a variation to change this to a Great Britain orphan MA.

UK Specials Regulation

The UK’s Human Medicines Regulations 2012 allow for the manufacture and supply of medicinal products not 

authorized for marketing to patients with special needs at the request of the healthcare professional responsible for the 
patient’s care (these products are referred to as “specials”).  A special may only be supplied: (i) in response to an 
unsolicited order from a healthcare professional responsible for the care of the patient, (ii) if the product is manufactured 
and assembled in accordance with the specifications of that healthcare professional to fulfil the special needs of the 
individual patient which cannot be met by products already authorized for marketing, and (iii) if the product is 
manufactured under a specials license granted by the UK’s MHRA.

Manufacturing a special also imposes a five year record retention requirement subject to review by the MHRA,

including details of any suspected adverse reaction to the product so sold or supplied of which the person is aware or
subsequently becomes aware, as well as a continuing obligation to notify the MHRA of any suspected adverse reaction to
the medicinal product which is a serious adverse reaction.

Privacy and Data Protection Laws

We are also subject to laws and regulations in non-U.S. countries in which we are established or in which we run 

clinical trials, as well as countries in which we may sell, market and distribute products for which we obtain marketing 
approval. These laws and regulations cover data privacy and the protection of health-related and other personal data.  Laws 
and regulations in the EU and other jurisdictions apply broadly to the collection, use, storage, disclosure, processing and 
security of personal data, and have generally become more stringent over time.

For example, the General Data Protection Regulation, or GDPR, imposes strict requirements for processing the 

personal data of individuals within the EEA.  The GDPR allows EU member states to make additional laws and regulations 
further regulating the processing of genetic, biometric or health data.  Failure to comply with the requirements of GDPR 
and the applicable national data protection laws of the EU member states may result in fines of up to €20 million or up to 
4% of the total worldwide annual turnover of the preceding financial year, whichever is higher, and other administrative 
penalties and may expose us to compensation claims from affected individuals.

46

Table of Contents

Further, from January 1, 2021, we are subject to the GDPR and also the UK GDPR, which, together with the

amended UK Data Protection Act 2018, retains the GDPR in UK national law. The UK GDPR mirrors the fines under the
GDPR, e.g. fines up to the greater of £17.5 million or 4% of the total worldwide annual turnover of the preceding financial
year. The European Commission has adopted an adequacy decision in favor of the UK, enabling data transfers from EU
member states to the UK without additional safeguards. However, the UK adequacy decision will automatically expire in
June 2025 unless the European Commission re-assesses and renews/extends that decision, and it continues to remain under
review by the Commission during this period.

Employees

As of December 31, 2022, we had 358 employees, 343 of which are full-time employees. None of our employees 
is subject to a collective bargaining agreement or represented by a trade or labor union.  We consider our relationship with 
our employees to be good. 

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and
integrating our existing and new employees, advisors and consultants. The principal purposes of our equity incentive plans
are to attract, retain and reward personnel through the granting of equity-based compensation awards in order to increase
shareholder value and the success of our company by motivating such individuals to perform to the best of their abilities
and achieve our objectives.

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred significant losses since inception and anticipate that we will incur continued losses for the foreseeable
future, and may never achieve or maintain profitability.

We are a clinical stage company with limited operating history. We were formed and began operations in 2015.
We  have  never  been  profitable  and  do  not  expect  to  be  profitable  in  the  foreseeable  future.  We  have  incurred  net  losses
since  inception,  including  net  losses  of  approximately  $129.6  million  and  $79.6  million  for  the  twelve  months  ended
December  31,  2022  and  2021,  respectively.  As  of  December  31,  2022,  we  had  an  accumulated  deficit  of  approximately
$470.2  million.  Since  our  inception,  we  have  devoted  substantially  all  of  our  resources  to  developing  our  technology
platform,  establishing  our  viral  vector  manufacturing  facilities  and  plasmid  and  DNA  production  facility,  developing
manufacturing  processes,  advancing  the  product  candidates  in  our  ophthalmology,  salivary  gland  and  neurodegenerative
disease programs, research and development activities, building our intellectual property portfolio, organizing and staffing
our  company,  developing  our  business  plans,  raising  capital,  securing  debt  financing  and  providing  general  and
administrative support for these operations. We have not yet demonstrated an ability to successfully complete large-scale,
pivotal clinical trials, obtain marketing approval, manufacture product at a commercial scale, or arrange for a third party to
do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Given
the  length  of  time  typically  needed  to  develop  a  new  drug  from  the  time  it  enters  Phase  1  clinical  trials  to  when  it  is
approved for treating patients, predictions about our future success or viability may not be as accurate as they could be if
we had a longer operating history or a history of successfully developing and commercializing genetic medicine products.

We expect to continue to incur significant expenses and additional operating losses for the foreseeable future as
we  seek  to  advance  product  candidates  through  preclinical  and  clinical  development,  expand  our  research,  development
and  manufacturing  activities,  develop  new  product  candidates,  build  and  expand  our  intellectual  product  portfolio,
complete  clinical  trials,  seek  regulatory  approval  and,  if  we  receive  regulatory  approval,  commercialize  our  products.
Furthermore, the costs of advancing product candidates into each succeeding clinical phase tend to increase substantially
over time, including the ongoing Phase 3 Lumeos clinical trial of botaretigene sparoparvovec for the treatment of patients
with XLRP, although we believe that certain of these increases will be partially offset by the research funding in connection
with the Collaboration Agreement. In addition, we expect to continue incurring increasing research and development costs
associated with our clinical activities for AAV-hAQP1 for the treatment of radiation-induced xerostomia and xerostomia
associated with Sjogren’s syndrome, as well as for AAV-GAD for the treatment of Parkinson’s disease. The total costs to
advance any of our product candidates to marketing approval in even a single jurisdiction would be substantial. Because of
the  numerous  risks  and  uncertainties  associated  with  gene  therapy  product  development,  we  are  unable  to  accurately
predict  the  timing  or  amount  of  increased  expenses  or  whether  we  will  be  able  to  begin  generating  revenue  from  the
commercialization  of  products  or  achieve  or  maintain  profitability.  Our  expenses  have  and  will  continue  to  increase
substantially  as  a  public  company  and  as  we  continue  to  add  clinical,  scientific,  operational,  financial,  manufacturing,
compliance and management information systems and personnel, including personnel to support our product development,
manufacturing and planned future commercialization efforts.

Before  we  generate  any  revenue  from  product  sales,  each  of  our  programs  and  product  candidates  will  require
additional  preclinical  and/or  clinical  development,  potential  regulatory  approval  in  multiple  jurisdictions,  manufacturing,
building  of  a  commercial  organization,  substantial  investment  and  significant  marketing  efforts.  Our  expenses  could
increase  beyond  expectations  if  we  are  required  by  the  FDA,  MHRA,  EMA,  or  other  regulatory  authorities  to  perform
preclinical  studies  and  clinical  trials  in  addition  to  those  that  we  currently  anticipate.  These  risks  are  further  described
under “—Risks Related to Discovery, Development, Clinical Testing, Manufacturing and Regulatory Approval” and “—
Risks  Related  to  Commercialization.”  As  a  result,  we  expect  to  continue  to  incur  net  losses  for  the  foreseeable  future.
These net losses have had, and will continue to have, an adverse effect on our shareholders’ equity and working capital.

As  we  continue  to  build  our  business,  we  expect  our  financial  condition  and  operating  results  may  fluctuate
significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control.
Accordingly, you should not rely upon the results of any particular quarterly or annual period as indications of future

48

Table of Contents

operating performance. If we are unable to develop and commercialize one or more of our product candidates either alone
or with collaborators, or if revenues from any product candidate that receives marketing approval are insufficient, we will
not achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability. If we
are unable to achieve and then maintain profitability, the value of our equity securities will be adversely affected.

We will require additional capital to fund our operations, which may not be available on acceptable terms, if at all.

We  expect  to  spend  substantial  amounts  to  complete  the  development  of,  seek  regulatory  approvals  for  and
commercialize our product candidates, as well as continue to expand our manufacturing and supply chain capabilities. This
will require additional capital, which we may raise through equity offerings, debt financings, marketing and distribution
arrangements and other collaborations, strategic alliances and licensing arrangements or other sources. Our ability to raise
additional capital when needed has been and may in the future be adversely affected by external factors beyond our control,
including  changes  in  the  political  climate,  geopolitical  actions,  changes  in  market  interest  rates,  potential  reforms  and
changes  to  government  regulations,  the  effect  of  healthcare  reform  legislation,  including  those  that  may  limit  pricing  of
pharmaceutical  products  and  drugs,  market  prices  and  conditions,  prospects  for  favorable  or  unfavorable  clinical  trial
results, new product initiatives, the manufacturing and distribution of new products, product safety and efficacy issues, new
collaborations,  strategic  alliances  and  licensing  arrangements,  and  the  COVID-19  outbreak  and  mitigation  measures.
Furthermore,  we  expect  to  continue  to  incur  costs  associated  with  operating  as  a  public  company.  Adequate  additional
financing may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would
have a negative effect on our financial condition and our ability to pursue our business strategy. In addition, attempting to
secure additional financing has diverted and may in the future divert the time and attention of our management from day-
to-day activities and harm our product candidate development efforts. If we are unable to raise capital when needed or on
acceptable terms, we would be forced to delay, reduce or eliminate certain of our research and development programs.

Our operations have consumed significant amounts of cash since inception. As of December 31, 2022, our cash
and cash equivalents were $115.5 million. In addition, we expect to receive $21.3 million in receivables which we expect
to collect in the first quarter of 2023 from Janssen in connection with the Collaboration Agreement. Based on our cash and
cash equivalents at December 31, 2022 and the research funding and milestone payments we expect to receive under the
Collaboration Agreement, we estimate that such funds will be sufficient to enable us to fund our operating expenses and
capital expenditure requirements into the fourth quarter of 2024. This estimate is based on assumptions that may prove to
be wrong, and we could use our available capital resources sooner than we currently expect. Changing circumstances could
cause us to spend more than expected or consume capital significantly faster than we currently anticipate, such as inflation
or other factors that may significantly increase our business costs. Because the length of time and activities associated with
successful development of our product candidates is uncertain, we are unable to estimate the actual funds we will require
for development and any approved marketing and commercialization activities. Our future funding requirements, both near
and long-term, will depend on many factors, including, but not limited to:

● the  progress,  timing,  costs  and  results  of  our  ongoing  clinical  development  for  our  X-linked  retinitis
pigmentosa  product  candidate,  botaretigene  sparoparvovec,  including  the  ongoing  Phase  3  Lumeos
clinical  trial  of  botaretigene  sparoparvovec  for  the  treatment  of  patients  with  XLRP,  for  our  CNGB3
achromatopsia  gene  therapy  product  candidate,  AAV-CNGB3,  for  our  CNGA3  achromatopsia  gene
therapy product candidate, AAV-CNGA3, for our RPE65-associated retinal dystrophy product candidate,
AAV-RPE65,  and  to  continue  to  conduct  our  ongoing  natural  history  studies  for  inherited  retinal
diseases, or IRDs;

● the progress, timing, costs and results of our clinical development for our radiation-induced xerostomia
product candidate, AAV-hAQP1, and for our product candidate for the treatment of Parkinson’s disease,
AAV-GAD;

49

Table of Contents

● the  development  of  our  product  candidate  for  the  treatment  of  ALS,  AAV-UPF1,  for  our  product
candidate  for  the  treatment  of  xerostomia  associated  with  Sjogren’s  syndrome,  AAV-hAQP1,  and  our
product candidate for the treatment of neovascular age related macular degeneration, or wet AMD;

● the  development  of  potentially  transformative  gene  regulation  technology  designed  to  precisely  and
specifically  control  gene  therapy  expression  levels  via  dose-response  to  orally  delivered  small
molecules;

● continuing  our  current  research  programs  and  our  preclinical  development  of  product  candidates  from

our current research programs;

● seeking to identify, assess, acquire and/or develop additional research programs and additional product

candidates;

● the preclinical testing and clinical trials for any product candidates we identify and develop;

● the outcome, timing and cost of meeting regulatory requirements established by the FDA, MHRA, EMA

and other regulatory authorities;

● the  cost  of  expanding  and  protecting  our  intellectual  property  portfolio,  including  filing,  prosecuting,

defending and enforcing our patent claims and other intellectual property rights;

● the  cost  of  defending  potential  intellectual  property  disputes,  including  patent  infringement  actions

brought by third parties against us or any of our product candidates;

● the effect of competing technological and market developments;

● the cost of further developing and scaling our manufacturing facilities and processes;

● the cost and timing of completion of commercial-scale manufacturing facilities and activities;

● the  cost  of  making  royalty,  milestone  or  other  payments  under  current  and  any  future  in-license

agreements;

● our  ability  to  establish  and  maintain  strategic  collaborations,  licensing  or  other  agreements  and  the

financial terms of such agreements;

● the  extent  to  which  we  in-license  or  acquire  rights  to  other  products,  product  candidates  and

technologies;

● the  cost  of  establishing  sales,  marketing  and  distribution  capabilities  for  our  product  candidates  in

regions where we choose to commercialize our products; and

● the  initiation,  progress,  timing  and  results  of  our  commercialization  of  our  product  candidates,  if

approved for commercial sale.

Raising  additional  capital  through  the  sale  of  equity  or  convertible  debt  securities  will  dilute  your  ownership
interest, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a
shareholder. For example, in connection with entering into the Financing Agreement (as defined below), we issued

50

warrants to Perceptive (as defined below), to purchase 400,000 ordinary shares at an exercise price of $15.00 per share and
300,000 ordinary shares at an exercise price of $20.00 per share. Additional debt financing or preferred equity financing, if
available, may involve agreements that include covenants further limiting or restricting our ability to take specific actions,
such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through
collaborations,  strategic  alliances  or  marketing,  distribution  or  licensing  arrangements  with  third  parties,  we  may  be
required to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant licenses on
terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when
needed,  we  may  be  required  to  delay,  limit,  reduce  or  terminate  our  product  development  or  future  commercialization
efforts  or  grant  rights  to  develop  and  market  product  candidates  that  we  would  otherwise  prefer  to  develop  and  market
ourselves.

We may not have sufficient cash flows or cash on hand to satisfy our debt obligations or covenants under our financing
arrangements, or we may not be able to effectively manage our business in compliance with such covenants.

On August 2, 2022, we, as borrower, and our wholly-owned subsidiaries MeiraGTx UK II Limited and MeiraGTx
Ireland  DAC,  as  guarantors  (the  “Subsidiary  Guarantors”),  entered  into  a  senior  secured  financing  arrangement  (the
“Financing Agreement”) by and among us, the Subsidiary Guarantors, the lenders and other parties from time to time party
thereto and Perceptive Credit Holdings III, LP, as administrative agent and lender (“Perceptive”). On December 19, 2022,
the Financing Agreement was converted to a note purchase agreement (the “Note Purchase Agreement”) between the same
parties  and  under  substantially  the  same  terms  and  conditions  as  the  Financing  Agreement,  subject  to  certain  customary
note constitution terms. The Note Purchase Agreement provides for an initial $75 million notes issuance (the “Tranche 1
Notes”),  and  we  may  request  an  additional  $25  million  notes  issuance  to  be  made  at  Perceptive’s  sole  discretion  before
August 2, 2024 (the “Tranche 2 Notes”, together with the Tranche 1 Notes, the “Notes”). The Notes incur interest, subject
to  certain  provisions  therein,  at  a  fluctuating  rate  per  annum  equal  to  10.00%  plus  the  secured  overnight  financing  rate
administered by the Federal Reserve Bank of New York for a one-month tenor, subject to a 1.00% floor. The Note Purchase
Agreement matures on August 2, 2026 and is interest-only during the term. The Note Purchase Agreement also contains
various  restrictions  and  covenants,  including,  among  other  things,  covenants  regarding  the  incurrence  of  additional
indebtedness,  limitations  on  liens,  limitations  on  certain  investments,  limitations  on  making  distributions,  dividends  and
other payments, mergers, consolidations and acquisitions, dispositions of assets, maintenance of at least $3.0 million in a
U.S. bank account, transactions with affiliates, changes to governing documents, changes to certain agreements and leases
and changes in control. Our obligations under the Note Purchase Agreement are secured by our London, UK and Shannon,
Ireland  manufacturing  facilities,  $3.0  million  of  our  cash  and  the  bank  accounts  of  the  Subsidiary  Guarantors,  and  the
issued and outstanding equity interests of the Subsidiary Guarantors.

There  can  be  no  assurance  that  Perceptive  will  elect  to  issue  the  Tranche  2  Notes  or  that  our  cash  and  cash
equivalents  available  under  the  Note  Purchase  Agreement  and  under  any  future  financings,  together  with  any  funds
generated  by  our  operations,  will  be  sufficient  to  satisfy  our  debt  payment  obligations.  Our  inability  to  generate  funds,
obtain financing sufficient to satisfy our debt payment obligations or remain in compliance with the debt covenants may
result  in  such  obligations  being  accelerated  by  our  lenders,  which  would  likely  have  a  material  adverse  effect  on  our
business, financial condition and results of operations.

The covenants may restrict our current and future operations, particularly our ability to respond to certain changes
in our business or industry, or take future actions. Additionally, our ability to comply with these restrictive covenants may
be impacted by events beyond our control, such as economic conditions or major central bank policy actions. Our Note
Purchase Agreement provides that our breach or failure to satisfy certain covenants constitutes an event of default. Upon
the  occurrence  of  an  event  of  default,  in  addition  to  an  increase  in  the  rate  of  interest  on  the  Notes  of  3%  per  annum,
Perceptive could elect to declare all amounts outstanding thereunder to be immediately due and payable, proceed against
the assets we provided as collateral, and, if such debt were accelerated, we may not have sufficient cash on hand or be able
to sell sufficient collateral to repay it, which would have an immediate adverse effect on our business and operating results.
This could potentially cause us to cease operations and result in a complete loss of your investment in our ordinary shares.

We are heavily dependent on the success of our Most Advanced Product Candidates, which are still in development, and
if none of them receive regulatory approval or are successfully commercialized, our business may be harmed.

Our future success and ability to generate product revenue is substantially dependent on our ability to successfully
develop,  obtain  regulatory  approval  for  and  successfully  commercialize  our  product  candidates.  We  currently  have  no
products that are approved for commercial sale and may never be able to develop marketable products. We have invested
and  expect  to  continue  to  invest  a  meaningful  portion  of  our  efforts  and  expenditures  over  the  next  few  years  in  the
development of botaretigene sparoparvovec, AAV-GAD, AAV-CNGB3, AAV-CNGA3, AAV-RPE65 and AAV-hAQP1 (the
“Most  Advanced  Product  Candidates”),  which  will  require  additional  clinical  development,  management  of  clinical  and
manufacturing  activities,  regulatory  approval  in  multiple  jurisdictions,  manufacturing  sufficient  supply,  building  of  a
commercial  organization,  substantial  investment  and  significant  marketing  efforts  before  we  can  generate  any  revenues
from  any  commercial  sales.  While  we  have  entered  into  a  Collaboration  Agreement  with  Janssen  with  respect  to  AAV-
CNGB3,  AAV-CNGA3  and  botaretigene  sparoparvovec,  pursuant  to  which  we  received  a  $100  million  upfront  payment
and  will  also  receive  funding  for  certain  research,  manufacturing,  clinical  development  and  commercialization  costs,
potential  additional  milestone  payments  upon  the  achievement  of  such  milestones  and  royalties  on  future  net  sales  of
products, there can be no assurance that these three product candidates will be successfully developed and commercialized
by us and Janssen. We cannot be certain that our Most Advanced Product Candidates will be successful in clinical trials,
receive regulatory approval or be successfully commercialized even if we receive regulatory approval. Even if we receive
approval to market our Most Advanced Product Candidates from the FDA, MHRA or other regulatory bodies, we cannot
be certain that our product candidates will be successfully commercialized by us or our collaborators, widely accepted in
the  marketplace  or  more  effective  than  other  commercially  available  alternatives.  Additionally,  the  research,  testing,
manufacturing, labeling, approval, sale, marketing and distribution of gene therapy products are and will remain subject to
extensive and evolving regulation by the FDA, MHRA and other regulatory authorities. We are not permitted to market our
Most Advanced Product Candidates in the United States until they receive approval of a biologics license application, or
BLA, from the FDA, we cannot market them in the UK or EU until we receive approval for an MA, from the MHRA or
European  Commission,  respectively,  and  we  cannot  market  them  in  other  countries  until  we  receive  any  other  required
regulatory approval in those countries.

Because  some  of  our  other  product  candidates  are  based  on  similar  technology  as  our  Most  Advanced  Product
Candidates, if any of our product candidates show unexpected adverse events or a lack of efficacy in the indications we
intend to treat, or if we experience other regulatory or developmental issues, our development plans and business could be
significantly  harmed.  Further,  competitors  may  be  developing  products  with  similar  technology  and  may  experience
problems with their products that could identify problems that would potentially harm our business.

We may not be successful in our efforts to identify additional product candidates.

Part  of  our  strategy  involves  identifying  novel  product  candidates.  The  process  by  which  we  identify  product
candidates may fail to yield product candidates for clinical development for a number of reasons, including those discussed
in these risk factors and also:

● we may not be able to assemble sufficient resources to acquire or discover additional product candidates;

● competitors  may  develop  alternatives  that  render  our  potential  product  candidates  obsolete  or  less

attractive;

● potential product candidates we develop may nevertheless be covered by third parties’ patents or other

exclusive rights;

● potential product candidates may, on further study, be shown to have harmful side effects, toxicities or
other  characteristics  that  indicate  that  they  are  unlikely  to  be  products  that  will  receive  marketing
approval and achieve market acceptance;

52

Table of Contents

● potential product candidates may not be effective in treating their targeted diseases;

● the  market  for  a  potential  product  candidate  may  change  so  that  the  continued  development  of  that

product candidate is no longer reasonable;

● a  potential  product  candidate  may  not  be  capable  of  being  produced  in  commercial  quantities  at  an

acceptable cost, or at all; or

● the regulatory pathway for a potential product candidate may be too complex and difficult to navigate

successfully or economically.

In  addition,  we  may  choose  to  focus  our  efforts  and  resources  on  a  potential  product  candidate  that  ultimately
proves  to  be  unsuccessful.  As  a  result,  we  may  fail  to  capitalize  on  viable  commercial  products  or  profitable  market
opportunities, be required to forego or delay pursuit of opportunities with other product candidates or other diseases that
may  later  prove  to  have  greater  commercial  potential,  or  relinquish  valuable  rights  to  such  product  candidates  through
collaboration, licensing or other royalty arrangements in cases in which it would have been advantageous for us to retain
sole  development  and  commercialization  rights.  If  we  are  unable  to  identify  additional  suitable  product  candidates  for
clinical  development,  this  would  adversely  impact  our  business  strategy  and  our  financial  position  and  share  price  and
could potentially cause us to cease operations.

Risks Related to Discovery, Development, Clinical Testing, Manufacturing and Regulatory Approval

COVID-19 has impacted and may continue to impact our business, and any other pandemic, epidemic or outbreak of an
infectious disease may materially and adversely impact our business, including our preclinical studies, clinical trials,
manufacturing capabilities and regulatory approvals.

As  a  result  of  the  COVID-19  pandemic,  we  have  at  times  restricted  onsite  activities  and  have  also  experienced
some delays in enrolling, treating and monitoring patients in our clinical trials, as well as limited supply chain disruptions.
We may experience these or other disruptions from the COVID-19 pandemic or other pandemic, epidemic or outbreak of
an  infectious  disease  that  could  severely  impact  our  business,  preclinical  studies,  clinical  trials  and  laboratory  and
manufacturing activities, including, for example, delays or difficulties in enrolling patients in our clinical trials, delays or
difficulties  in  clinical  site  initiation,  including  difficulties  in  recruiting  clinical  site  investigators  and  clinical  site  staff,
diversion of healthcare resources away from the conduct of clinical trials, interruption of key clinical trial activities due to
limitations on travel imposed or recommended by regulatory authorities or others, interruption or delays in the operations
of the FDA, MHRA, EMA or other regulatory authorities, interruption of, or delays in, the manufacturing of our product
candidates, interruptions in preclinical studies due to restricted or limited operations at our laboratory facilities, limitations
on employee resources that would otherwise be focused on the conduct of our preclinical studies and clinical trials, and
interruption or delays to our sourced discovery and clinical activities.

The  COVID-19  pandemic  continues  to  impact  businesses  globally.  The  extent  to  which  the  outbreak  or  any
variants may further impact our business, preclinical studies, clinical trials and laboratory and manufacturing activities will
depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration
of the pandemic, the timing, distribution and effectiveness of vaccines, vaccination rates, travel restrictions and physical
distancing  requirements  in  the  countries  where  we  do  business,  business  closures  or  business  disruptions,  and  the
effectiveness  of  actions  taken  in  the  countries  where  we  do  business  to  contain  and  treat  the  disease,  respond  to  the
reduction  in  global  economic  activity  and  resume  normal  economic  and  operating  conditions.  If  we  or  any  of  the  third
parties  with  whom  we  engage  experience  prolonged  shutdowns  or  other  business  disruptions,  our  ability  to  conduct  our
business in the manner and on the timelines presently planned could be materially and negatively impacted. Furthermore,
the magnitude of the economic impact of COVID-19 pandemic and its variants including sustained inflation, supply chain
disruptions, and major central bank policy actions continues to be difficult to assess or predict and may continue to result in
significant disruption of global financial markets, which could materially affect our performance, financial condition,

53

Table of Contents

results  of  operations,  and  cash  flows,  as  well  as  our  ability  to  raise  additional  capital.  Additionally,  major  central  bank
policy actions may have a negative impact on our payment obligations under the Note Purchase Agreement.

It is difficult to predict the time and cost of product candidate development on our novel gene therapy platform. Very few
gene therapies have been approved in the United States or in Europe.

We have concentrated a portion of our research and development efforts on our gene therapy platform, which uses
both transduction and gene control technology. Our future success depends on the successful development of these novel
therapeutic approaches. To date, very few products that utilize gene transfer have been approved in the United States or
Europe.

Our gene therapy platform is based on a suite of viral vectors which we can deploy with gene therapy constructs,
which relies on the ability of AAV to efficiently transmit a therapeutic gene to certain kinds of cells. The mechanism of
action by which these vectors target particular tissues is still not completely understood. Therefore, it is difficult for us to
determine  that  our  vectors  will  be  able  to  properly  deliver  gene  transfer  constructs  to  enough  tissue  cells  to  reach
therapeutic levels. We cannot be certain that animal models will exist for some of the diseases we expect to pursue, that our
viral vectors will be able to meet safety and efficacy levels needed to be therapeutic in humans or that they will not cause
significant adverse events or toxicities. Furthermore, prior work conducted by a third party in non-human primates suggests
that intravenous, or IV, delivery of certain AAV vectors at very high doses may result in severe toxicity. The indications
that we target do not use IV administration for viral vector delivery and do not use doses as high as those tested in these
publications,  and  to  date  we  have  not  observed  the  severe  toxicities  described  in  these  publications  with  the  naturally
occurring AAV vectors that we use. However, we cannot be certain that we will be able to avoid triggering toxicities in our
future preclinical studies or clinical trials. Any such results could impact our ability to develop a product candidate. As a
result  of  these  factors,  it  is  more  difficult  for  us  to  predict  the  time  and  cost  of  product  candidate  development,  and  we
cannot predict whether the application of our gene therapy platform, or any similar or competitive gene therapy platforms,
will result in the identification, development, and regulatory approval of any product candidates, or that other gene therapy
technologies will not be considered better or more attractive. There can be no assurance that any development problems we
experience  in  the  future  related  to  our  gene  therapy  platform  or  any  of  our  research  programs  will  not  cause  significant
delays or unanticipated costs, or that such development problems can be solved. Any of these factors may prevent us from
completing our preclinical studies or clinical trials or commercializing any product candidates we may develop on a timely
or profitable basis, if at all.

In  addition,  because  our  gene  regulation  technology  is  still  in  the  research  stage,  we  have  not  yet  been  able  to

assess safety in humans, and there may be long-term effects from treatment that we cannot predict at this time.

Because gene therapy is novel and the regulatory landscape that governs any product candidates we may develop is
uncertain and may change, we cannot predict the time and cost of obtaining regulatory approval, if we receive it at all,
for any product candidates we may develop.

The  regulatory  requirements  that  will  govern  any  novel  gene  therapy  product  candidates  we  develop  are  not
entirely  clear  and  may  change.  Within  the  broader  genetic  medicine  field,  very  few  therapeutic  products  have  received
marketing authorization from the FDA, MHRA and European Commission. Even with respect to more established products
that  fit  into  the  categories  of  gene  therapies  or  cell  therapies,  the  regulatory  landscape  is  still  developing.  Regulatory
requirements governing gene therapy products and cell therapy products have changed frequently and will likely continue
to  change  in  the  future.  Moreover,  there  is  substantial,  and  sometimes  uncoordinated,  overlap  in  those  responsible  for
regulation  of  existing  gene  therapy  products  and  cell  therapy  products,  which  could  impact  the  timing  and  cost  of  any
regulatory  approval.  For  example,  in  the  United  States,  the  FDA  has  established  the  Office  of  Tissues  and  Advanced
Therapies within its Center for Biologics Evaluation and Research, or CBER, to consolidate the review of gene therapy and
related products, and the Cellular, Tissue and Gene Therapies Advisory Committee to advise CBER on its review. Gene
therapy clinical trials are also subject to review and oversight by an institutional biosafety committee, or IBC, and/or

54

Table of Contents

an  institutional  review  board,  or  IRB,  which  are  local  institutional  committees  or  boards,  as  applicable,  that  review,
approve and oversee basic and clinical research conducted at the institution participating in the clinical trial.

In the EU, the EMA’s Committee for Advanced Therapies, or CAT, is responsible for assessing the quality, safety,
and  efficacy  of  ATMPs.  ATMPs  include  gene  therapy  medicines,  somatic-cell  therapy  medicines  and  tissue-engineered
medicines.  The  role  of  the  CAT  is  to  prepare  a  draft  opinion  on  an  application  for  marketing  authorization  for  a  gene
therapy medicinal candidate that is submitted to the EMA. In the EU, the development and evaluation of a gene therapy
product must be considered in the context of the relevant EU guidelines. The EMA may issue new guidelines concerning
the  development  and  marketing  authorization  for  gene  therapy  products  and  require  that  we  comply  with  these  new
guidelines. As a result, the procedures and standards applied to gene therapy products and cell therapy products may be
applied to any gene therapy product candidate we may develop, but that remains uncertain at this point.

Post  Brexit,  MAAs  for  ATMPs  in  Great  Britain  are  regulated  nationally  and  assessed  in  accordance  with  the
general provisions in place for the licensing of medicines, taking the specific requirements for this group of medicines into
account. In Northern Ireland, ATMPs continue to be authorized according to the EU’s centralized procedure. Definitions
for  individual  classes  of  ATMPs  remain  unchanged  and  classification  of  ATMPs  are  undertaken  by  the  MHRA  in
accordance with EU legislation and current guidance from CAT. Data, traceability, exemptions from licensing, packaging
and post-authorization requirements remain in line with EU requirements transposed into UK law. However, if the EMA
issues  new  guidance  on  ATMPs  going  forward,  there  is  a  risk  of  regulatory  divergence  with  the  MHRA  and  separate
procedures and standards with which we may need to comply.

Adverse developments in preclinical studies or clinical trials conducted by others in the field of gene therapy and
gene regulation products may cause the FDA, MHRA and other regulatory bodies to revise the requirements for approval
of  any  product  candidates  we  may  develop  or  limit  the  use  of  products  utilizing  gene  regulation  technologies,  either  of
which  could  harm  our  business.  In  addition,  the  clinical  trial  requirements  of  the  FDA,  MHRA  and  other  regulatory
authorities  and  the  criteria  these  regulators  use  to  determine  the  safety  and  efficacy  of  a  product  candidate  vary
substantially  according  to  the  type,  complexity,  novelty,  and  intended  use  and  market  of  the  potential  products.  The
regulatory  approval  process  for  product  candidates  such  as  ours  can  be  more  expensive  and  take  longer  than  for  other,
better known, or more extensively studied pharmaceutical or other product candidates. Further, as we are developing novel
treatments  for  diseases  in  which  there  is  little  clinical  experience  with  new  endpoints  and  methodologies,  there  is
heightened  risk  that  the  FDA,  MHRA,  EMA  or  other  regulatory  bodies  may  not  consider  the  clinical  trial  endpoints  to
provide  clinically  meaningful  results,  and  the  resulting  clinical  data  and  results  may  be  more  difficult  to  analyze.  The
prospectively  designed  natural  history  studies  with  the  same  endpoints  as  our  corresponding  clinical  trials  may  not  be
accepted by the FDA, MHRA, EMA or other regulatory authorities. Regulatory agencies administering existing or future
regulations  or  legislation  may  not  allow  production  and  marketing  of  products  utilizing  gene  regulation  technology  in  a
timely manner or under technically or commercially feasible conditions. In addition, regulatory action or private litigation
could  result  in  expenses,  delays,  or  other  impediments  to  our  research  programs  or  the  commercialization  of  resulting
products.

The regulatory review committees and advisory groups described above and the new guidelines they promulgate
may lengthen the regulatory review process, require us to perform additional preclinical studies or clinical trials, increase
our  development  costs,  lead  to  changes  in  regulatory  positions  and  interpretations,  delay  or  prevent  approval  and
commercialization  of  these  treatment  candidates,  or  lead  to  significant  post-approval  limitations  or  restrictions.  As  we
advance our research programs and develop future product candidates, we will be required to consult with these regulatory
and  advisory  groups  and  to  comply  with  applicable  guidelines.  If  we  fail  to  do  so,  we  may  be  required  to  delay  or
discontinue development of any product candidates we identify and develop.

Clinical trials are expensive, time-consuming, difficult to design and implement, and involve an uncertain outcome.
Further, we may encounter substantial delays in our clinical trials.

The clinical trials and manufacturing of our product candidates are, and the manufacturing and marketing of our
products, if approved, will be, subject to extensive and rigorous review and regulation by numerous government authorities

55

Table of Contents

in the United States and in other countries where we intend to test and market our product candidates. Before obtaining
regulatory  approvals  for  the  commercial  sale  of  any  of  our  product  candidates,  we  must  demonstrate  through  lengthy,
complex and expensive preclinical testing and clinical trials that our product candidates are both safe and effective for use
in each target indication. In particular, because our product candidates are subject to regulation as biological drug products,
we will need to demonstrate that they are safe, pure, and potent for use in their target indications. Each product candidate
must demonstrate an adequate risk versus benefit profile in its intended patient population and for its intended use.

Clinical testing is expensive, can take many years to complete and is subject to uncertainty. We cannot guarantee
that any clinical trials will be conducted as planned or completed on schedule, if at all. Failure can occur at any time during
the clinical trial process. Even if our future clinical trials are completed as planned, we cannot be certain that their results
will support the safety and effectiveness of our product candidates for their targeted indications. Our future clinical trial
results may not be successful.

In  addition,  even  if  such  trials  are  successfully  completed,  we  cannot  guarantee  that  the  FDA,  MHRA,  EMA  or
other  regulatory  authorities  will  interpret  the  results  as  we  do,  and  more  trials  could  be  required  before  we  submit  our
product candidates for approval. To the extent that the results of the trials are not satisfactory to the FDA, MHRA, EMA or
other regulatory authorities for support of an MAA, we may be required to expend significant resources, which may not be
available to us, to conduct additional trials in support of potential approval of our product candidates.

To date, we have not completed any clinical development programs required for the approval of any of our product
candidates.  Although  we  are  currently  conducting  several  clinical  development  programs,  we  may  experience  delays  in
conducting any clinical trials and we do not know whether our ongoing and future clinical trials will begin on time, need to
be redesigned, be able to recruit and enroll patients on time or be completed on schedule, or at all. Events that may prevent
successful or timely completion of clinical development include:

● inability  to  generate  sufficient  preclinical,  toxicology,  or  other  in  vivo  or  in  vitro  data  to  support  the

initiation of clinical trials;

● delays  in  sufficiently  developing,  characterizing  or  controlling  a  manufacturing  process  suitable  for

advanced clinical trials;

● delays in developing suitable assays for screening patients for eligibility for trials with respect to certain

product candidates;

● delays in reaching agreement with the FDA, MHRA or other regulatory authorities as to the design or
implementation of our clinical trials and obtaining regulatory approval to commence a clinical trial;

● inability  to  reach  an  agreement  on  acceptable  terms  with  clinical  trial  sites  or  prospective  contract
research  organizations,  or  CROs,  the  terms  of  which  can  be  subject  to  extensive  negotiation  and  may
vary significantly among different clinical trial sites;

● our  inability  to  recruit  and  train  clinical  trial  investigators  with  the  appropriate  competencies  and
experience  to  conduct  the  clinical  trials,  administer  our  product  candidates  and  oversee  clinical  trial
staff;

● delays in obtaining IRB or ethics committee approval or positive opinion at each site;

● inability to recruit suitable patients to participate in a clinical trial;

● inability to develop and validate the companion diagnostic to be used in a clinical trial, if applicable;

56

Table of Contents

● delays  in  sufficiently  developing,  designing  and  manufacturing  equipment  or  medical  devices  used  in

our clinical trials;

● patients not completing a clinical trial or returning for post-treatment follow-up;

● clinical sites, CROs, or other third parties deviating from trial protocol or dropping out of a trial;

● failure  to  perform  in  accordance  with  the  FDA’s  good  clinical  practice,  or  GCP,  requirements,  or

applicable regulatory guidelines in other countries;

● addressing patient safety concerns that arise during the course of a trial, including occurrence of adverse

events associated with the product candidate that are viewed to outweigh its potential benefits;

● having an insufficient number of clinical trial sites; or

● inability to manufacture sufficient quantities of our product candidates for use in clinical trials.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent
our ability to receive marketing approval or commercialize our product candidates or significantly increase the cost of such
trials, including:

● we may experience changes in regulatory requirements or guidance, or receive feedback from regulatory

authorities that requires us to modify the design of our clinical trials;

● clinical  trials  of  our  product  candidates  may  produce  negative  or  inconclusive  results,  and  we  may
decide,  or  regulators  may  require  us,  to  conduct  additional  clinical  trials  or  abandon  development
programs;

● the  number  of  patients  required  for  clinical  trials  of  our  product  candidates  may  be  larger  than  we
anticipate, enrollment in these clinical trials may be slower than we anticipate, or participants may drop
out of these clinical trials at a higher rate than we anticipate;

● our  third-party  contractors  may  fail  to  comply  with  regulatory  requirements  or  meet  their  contractual

obligations to us in a timely manner, or at all;

● we or our investigators might have to suspend or terminate clinical trials of our product candidates for
various  reasons,  including  non-compliance  with  regulatory  requirements,  a  finding  that  our  product
candidates  have  undesirable  side  effects  or  other  unexpected  characteristics,  or  a  finding  that  the
participants are being exposed to unacceptable health risks;

● the cost of clinical trials of our product candidates may be greater than we anticipate, and we may not

have funds to cover the costs;

● the supply or quality of our product candidates or other materials necessary to conduct clinical trials of

our product candidates may be insufficient or inadequate;

● business interruptions resulting from geopolitical actions, including war and terrorism, or a widespread
health  emergency,  such  as  the  COVID-19  pandemic,  or  natural  disasters  including  earthquakes,
typhoons, floods and fires, or from economic or political instability; and

57

Table of Contents

● any  future  collaborators  that  conduct  clinical  trials  may  face  any  of  the  above  issues,  and  they  may

conduct clinical trials in ways they view as advantageous to them but that are suboptimal for us.

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that
we  currently  contemplate,  if  we  are  unable  to  successfully  complete  clinical  trials  of  our  product  candidates  or  other
testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we
may:

● incur unplanned costs;

● be delayed in obtaining marketing approval for our product candidates or not obtain marketing approval

at all;

● obtain marketing approval in some countries and not in others;

● obtain  marketing  approval  for  indications  or  patient  populations  that  are  not  as  broad  as  intended  or

desired;

● obtain marketing approval with labeling that includes significant use or distribution restrictions or safety

warnings, including boxed warnings;

● be subject to additional post-marketing testing requirements; or

● have the product removed from the market after obtaining marketing approval.

We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in
which  such  trials  are  being  conducted,  by  the  Data  Safety  Monitoring  Board,  or  DSMB,  for  such  trial  or  by  the  FDA,
MHRA  or  other  foreign  regulatory  authorities.  Such  authorities  may  impose  such  a  suspension  or  termination  due  to  a
number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical
protocols, inspection of the clinical trial operations or trial site by the FDA, MHRA or other regulatory authorities resulting
in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from
using  a  drug,  changes  in  governmental  regulations  or  administrative  actions  or  lack  of  adequate  funding  to  continue  the
clinical trial.

Our Most Advanced Product Candidates will require extensive clinical testing before we are prepared to submit a
BLA  or  MAA  for  regulatory  approval.  We  cannot  predict  with  any  certainty  if  or  when  we  might  complete  the  clinical
development  for  our  product  candidates  and  submit  a  BLA  or  MAA  for  regulatory  approval  of  any  of  our  product
candidates or whether any such BLA or MAA will be approved. We may also seek feedback from the FDA, MHRA, EMA
or  other  regulatory  authorities  on  our  clinical  development  program,  and  the  FDA,  MHRA,  EMA  or  such  regulatory
authorities may not provide such feedback on a timely basis, or such feedback may not be favorable, which could further
delay our development programs.

If we experience delays in the commencement or completion of our clinical trials, or if we terminate a clinical trial
prior  to  completion,  the  commercial  prospects  of  our  product  candidates  could  be  harmed,  and  our  ability  to  generate
revenues from our product candidates may be delayed. In addition, any delays in our clinical trials could increase our costs,
slow  down  the  development  and  approval  process  and  jeopardize  our  ability  to  commence  product  sales  and  generate
revenues. Any of these occurrences may harm our business, financial condition and results of operations. In addition, many
of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead
to the denial of regulatory approval of our product candidates.

In  addition,  the  FDA’s  and  other  regulatory  authorities’  policies  with  respect  to  clinical  trials  may  change  and
additional government regulations may be enacted. For instance, the regulatory landscape related to clinical trials in the EU
recently  evolved.  The  CTR  adopted  in  April  2014  became  applicable  on  January  31,  2022  and  repeals  the  EU  Clinical
Trials Directive. While the EU Clinical Trials Directive required a separate CTA to be submitted in each member state in
which the clinical trial takes place, to both the competent national health authority and an independent ethics committee,
the CTR introduces a centralized process and only requires the submission of a single application for multi-center trials.
The CTR allows sponsors to make a single submission to both the competent authority and an ethics committee in each
member state, leading to a single decision per member state. The assessment procedure of the CTA has been harmonized as
well, including a joint assessment by all member states concerned, and a separate assessment by each member state with
respect  to  specific  requirements  related  to  its  own  territory,  including  ethics  rules.  Each  member  state’s  decision  is
communicated to the sponsor via the centralized EU portal. Once the CTA is approved, clinical study development may
proceed.  The  CTR  foresees  a  three-year  transition  period.  The  extent  to  which  ongoing  and  new  clinical  trials  will  be
governed by the CTR varies. Clinical trials for which an application was submitted (i) prior to January 31, 2022 under the
EU Clinical Trials Directive, or (ii) between January 31, 2022 and January 31, 2023 and for which the sponsor has opted
for the application of the EU Clinical Trials Directive remain governed by said EU Clinical Trials Directive until January
31, 2025. After this date, all clinical trials (including those which are ongoing) will become subject to the provisions of the
CTR. Compliance with the CTR requirements by us and our third-party service providers, such as CROs, may impact our
development plans.  

It  is  currently  unclear  to  what  extent  the  UK  will  seek  to  align  its  regulations  with  the  EU.  The  UK  regulatory
framework  in  relation  to  clinical  trials  is  derived  from  existing  EU  legislation  (as  implemented  into  UK  law,  through
secondary  legislation).  On  January  17,  2022,  the  MHRA  launched  an  eight-week  consultation  on  reframing  the  UK
legislation for clinical trials. The consultation closed on March 14, 2022 and aims to streamline clinical trials approvals,
enable innovation, enhance clinical trials transparency, enable greater risk proportionality, and promote patient and public
involvement in clinical trials. The outcome of the consultation is being closely watched and will determine whether the UK
chooses  to  align  with  the  CTR  or  diverge  from  it  to  maintain  regulatory  flexibility.  Under  the  terms  of  the  Protocol  on
Ireland  and  Northern  Ireland,  provisions  of  the  CTR  which  relate  to  the  manufacture  and  import  of  investigational
medicinal products and auxiliary medicinal products currently apply in Northern Ireland. On February 27, 2023, the UK
Government and the European Commission reached a political agreement on the “Windsor Agreement” which may revise
the Protocol on Ireland and Northern Ireland in order to address some of the perceived shortcomings in its operation. If
implemented, this may have further impact on the application of the CTR in Northern Ireland. A decision by the UK not to
closely  align  its  regulations  with  the  new  approach  that  will  be  adopted  in  the  EU  may  have  an  effect  on  the  cost  of
conducting clinical trials in the UK as opposed to other countries.

If  we  are  slow  or  unable  to  adapt  to  changes  in  existing  requirements  or  the  adoption  of  new  requirements  or

policies governing clinical trials, our development plans may also be impacted.

The affected populations for our product candidates may be smaller than we or third parties currently project, which
may affect the addressable markets for our product candidates.

Our projections of the number of people who have the diseases we are seeking to treat, as well as the subset of
people  with  these  diseases  who  have  the  potential  to  benefit  from  treatment  with  our  product  candidates,  are  estimates
based  on  our  knowledge  and  understanding  of  these  diseases.  The  total  addressable  market  opportunity  for  our  product
candidates will ultimately depend upon a number of factors including the diagnosis and treatment criteria included in the
final label, if approved for sale in specified indications, acceptance by the medical community, patient access and product
pricing and reimbursement. Incidence and prevalence estimates are frequently based on information and assumptions that
are not exact and may not be appropriate, and the methodology is forward-looking and speculative. The process we have
used in developing an estimated incidence and prevalence range for the indications we are targeting has involved collating
limited  data  from  multiple  sources.  Accordingly,  the  incidence  and  prevalence  estimates  included,  or  supporting  the
information,  in  our  SEC  filings  and  other  materials  should  be  viewed  with  caution.  Further,  the  data  and  statistical
information included, or supporting the information, in our SEC filings and other materials, including estimates derived

59

Table of Contents

from them, may differ from information and estimates made by our competitors or from current or future studies conducted
by independent sources.

The  use  of  such  data  involves  risks  and  uncertainties  and  is  subject  to  change  based  on  various  factors.  Our
estimates may prove to be incorrect and new studies may change the estimated incidence or prevalence of the diseases we
seek  to  address.  The  number  of  patients  with  the  diseases  we  are  targeting  in  the  United  States,  the  UK,  the  EU  and
elsewhere may turn out to be lower than expected or may not be otherwise amenable to treatment with our products, or new
patients may become increasingly difficult to identify or access, all of which would harm our results of operations and our
business.

Negative public opinion of gene therapy and increased regulatory scrutiny of gene therapy and genetic research may
adversely impact public perception of our current and future product candidates.

Our  potential  therapeutic  products  involve  introducing  genetic  material  into  patients’  cells.  The  clinical  and
commercial success of our potential products will depend in part on public acceptance of the use of gene therapy and gene
regulation  for  the  prevention  or  treatment  of  human  diseases.  Public  attitudes  may  be  influenced  by  claims  that  gene
therapy and gene regulation are unsafe, unethical, or immoral, and, consequently, our products may not gain the acceptance
of  the  public  or  the  medical  community.  Public  attitudes  may  adversely  impact  our  ability  to  enroll  clinical  trials.
Moreover, our success will depend upon physicians prescribing, and their patients being willing to receive, treatments that
involve the use of product candidates we may develop in lieu of, or in addition to, existing treatments with which they are
already familiar and for which greater clinical data may be available.

More restrictive government regulations or negative public opinion would have a negative effect on our business or
financial condition and may delay or impair the development and commercialization of our product candidates or demand
for  any  products  once  approved.  For  example,  in  2003,  trials  using  early  versions  of  murine  gamma-retroviral  vectors,
which integrate with, and thereby alter, the host cell’s DNA, have led to several well-publicized adverse events, including
reported cases of leukemia. Although none of our current product candidates utilize murine gamma-retroviral vectors, our
product candidates use a viral delivery system. Adverse events in our clinical trials, even if not ultimately attributable to
our product candidates, and the resulting publicity could result in increased governmental regulation, unfavorable public
perception, potential regulatory delays in the testing or approval of our product candidates or the halting of clinical trials,
stricter labeling requirements for those product candidates that are approved and a decrease in demand for any such product
candidates. The risk of cancer remains a concern for gene therapy and we cannot assure that it will not occur in any of our
planned or future clinical trials. In addition, there is the potential risk of delayed adverse events following exposure to gene
therapy products due to persistent biological activity of the genetic material or other components of products used to carry
the genetic material. If any such adverse events occur, commercialization of our product candidates or further advancement
of our clinical trials could be halted or delayed, which would have a negative impact on our business and operations.

We may fail to maintain the benefits of certain regulatory designations that we have obtained for our product
candidates, and may in the future seek and fail to obtain such designations for other of our current or potential future
product candidates. Even if such designations are obtained, they may not lead to faster development or regulatory
review or approval, and they do not increase the likelihood that our product candidates will receive marketing approval.

A sponsor may seek approval of its product candidate under programs designed to accelerate the FDA’s review and
approval  of  new  drugs  and  biological  products  that  meet  certain  criteria.  For  example,  the  FDA  has  a  Fast  Track
designation  program  that  is  intended  to  expedite  or  facilitate  the  process  for  reviewing  new  products  that  meet  certain
criteria. Specifically, new drugs and biological products are eligible for Fast Track designation if they are intended to treat
a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs. Fast Track
designation applies to the combination of the product and the specific indication for which it is being studied. For product
candidates with Fast Track designation, sponsors may be eligible for more frequent meetings with the FDA to discuss the

60

Table of Contents

candidate’s development plan and more frequent written communication from the FDA about such things as the design of
the proposed clinical trials and use of biomarkers. In addition, the FDA may consider for review sections of the BlA on a
rolling  basis  before  the  complete  application  is  submitted  if  relevant  criteria  are  satisfied,  including  an  agreement  with
FDA on the proposed schedule for the submission of portions of the BLA, and the payment of applicable user fees before
FDA may initiate a review. Even if Fast Track designation is granted, it may be rescinded if the product no longer meets
the qualifying criteria. In April 2018, botaretigene sparoparvovec was issued Fast Track designation by the FDA for the
treatment of X-linked retinitis pigmentosa owing to defects in RPGR. In August 2018, AAV-CNGB3 was issued Fast Track
designation by the FDA for the treatment of achromatopsia caused by CNGB3 mutations. In January 2021, AAV-CNGA3
was issued Fast Track designation by the FDA for the treatment of achromatopsia caused by CNGA3 mutations.

Similarly,  the  EMA  has  established  the  PRIME  scheme  to  expedite  the  development  and  review  of  product
candidates that show a potential to address to a significant extent an unmet medical need, based on early clinical data. In
February  2018,  AAV-CNGB3  in  the  treatment  of  achromatopsia  associated  with  defects  in  CNGB3  was  admitted  to  the
PRIME  scheme  of  the  EMA.  In  February  2020,  botaretigene  sparoparvovec  for  the  treatment  of  X-linked  retinitis
pigmentosa owing to defects in RPGR was admitted to the PRIME scheme of the EMA.

A sponsor may also seek an RMAT designation for its product candidates. In 2017, the FDA established the RMAT
designation  as  part  of  its  implementation  of  the  21st  Century  Cures  Act.  A  biological  product  is  eligible  for  RMAT
designation if it qualifies as an RMAT, which is defined as a cell therapy, therapeutic tissue engineering product, human
cell  and  tissue  product,  or  any  combination  product  using  such  therapies  or  products,  with  limited  exceptions,  and  is
intended  to  treat,  modify,  reverse,  or  cure  a  serious  or  life-threatening  disease  or  condition  and  for  which  preliminary
clinical evidence indicates that the biological product has the potential to address unmet medical needs for such a disease
or condition. In a February 2019 guidance, the FDA also stated that certain gene therapies that lead to a sustained effect on
cells or tissues may meet the definition of a regenerative medicine therapy. RMAT designation provides potential benefits
that  include  more  frequent  meetings  with  the  FDA  to  discuss  the  development  plan  for  the  product  candidate,  and
eligibility for rolling review and priority review. Products granted RMAT designation may also be eligible for accelerated
approval  on  the  basis  of  a  surrogate  or  intermediate  endpoint  reasonably  likely  to  predict  long-term  clinical  benefit,  or
reliance upon data obtained from a meaningful number of sites, including through expansion to additional sites. RMAT-
designated products that receive accelerated approval may, as appropriate, fulfill their post-approval requirements through
the  submission  of  clinical  evidence,  clinical  trials,  patient  registries,  or  other  sources  of  real  world  evidence  (such  as
electronic health records); through the collection of larger confirmatory data sets; or via post-approval monitoring of all
patients treated with such therapy prior to approval of the therapy.

Such regulatory designations are within the discretion of the FDA, MHRA, EMA and other regulatory authorities.
Accordingly, even if we believe one of our product candidates meets the criteria for such regulatory programs designed to
accelerate  the  review  and  approval  of  new  drugs  and  we  seek  such  designations,  the  FDA,  MHRA,  EMA  or  other
applicable  regulatory  authority  may  disagree  and  instead  determine  not  to  make  such  designation  for  such  product
candidate. We cannot be sure that our evaluation of our product candidates as qualifying for such regulatory designations
will  meet  the  regulatory  authority’s  expectations.  In  any  event,  the  receipt  of  such  regulatory  designations  for  a  product
candidate may not result in a faster development process, review, or approval compared to product candidates considered
for approval under conventional regulatory procedures and does not assure ultimate approval by the regulatory authorities.
In addition, even if additional product candidates are granted such regulatory designations, the regulatory authority may
later decide that such product candidates no longer meet the conditions for qualification or decide that the time period for
review or approval will not be shortened.

We have received orphan drug designation from the FDA and European Commission for AAV-CNGB3, AAV-CNGA3,
AAV-RPE65, botaretigene sparoparvovec, AAV-AIPL1, AAV-RDH12 and from the FDA for AAV-hAQP1, and we may
seek orphan drug designation for additional product candidates in the future, but any orphan drug designations we
have received or may receive in the future may not confer marketing exclusivity or other expected benefits.

61

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is intended to treat a rare
disease  or  condition,  defined  as  one  occurring  in  a  patient  population  of  fewer  than  200,000  in  the  United  States,  or  a
patient  population  greater  than  200,000  in  the  United  States  where  there  is  no  reasonable  expectation  that  the  cost  of
developing the drug will be recovered from sales in the United States. In the EU, the European Commission grants orphan
designation  on  the  basis  of  the  EMA’s  Committee  for  Orphan  Medicinal  Products  opinion.  A  medicinal  product  may  be
designated  as  orphan  if  (1)  it  is  intended  for  the  diagnosis,  prevention  or  treatment  of  a  life-threatening  or  chronically
debilitating  condition;  (2)  either  (a)  such  condition  affects  no  more  than  five  in  10,000  persons  in  the  EU  when  the
application  is  made,  or  (b)  the  product,  without  the  benefits  derived  from  orphan  status,  would  not  generate  sufficient
return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment, of
such condition authorized for marketing in the EU, or if such a method exists, the product will be of significant benefit to
those affected by the condition.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant
funding towards clinical trial costs, tax credits for qualified clinical testing, and user-fee waivers. In addition, if a product
receives the first FDA approval of that drug for the indication for which it has orphan designation, the product is entitled to
orphan  drug  exclusivity,  which  means  the  FDA  may  not  approve  any  other  application  to  market  the  same  drug  for  the
same  disease  or  condition  for  a  period  of  seven  years,  except  in  limited  circumstances,  such  as  a  showing  of  clinical
superiority  over  the  product  with  orphan  exclusivity  or  where  the  manufacturer  is  unable  to  assure  the  availability  of
sufficient quantities of the orphan drug to meet the needs of patients with the rare disease or condition. Under the FDA’s
regulations,  the  FDA  will  deny  orphan  drug  exclusivity  to  a  designated  drug  upon  approval  if  the  FDA  has  already
approved  another  drug  with  the  same  principal  molecular  structural  features,  in  the  case  of  a  biologic,  for  the  same
indication,  unless  the  drug  is  demonstrated  to  be  clinically  superior  to  the  previously  approved  drug.  In  the  EU,  orphan
designation entitles a party to financial incentives such as reduction of fees or fee waivers, protocol assistance, and access
to the centralized MA procedure. Moreover, upon grant of an MA and assuming the requirement for orphan designation are
also met at the time the MA is granted, orphan medicinal products are entitled to a ten-year period of market exclusivity for
the  approved  therapeutic  indication.  The  period  of  market  exclusivity  is  extended  by  two  years  for  orphan  medicinal
products that have also complied with an agreed PIP. This period may be reduced to six years if, at the end of the fifth year,
the orphan designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not
to  justify  maintenance  of  market  exclusivity,  or  where  the  prevalence  of  the  condition  has  increased  above  the  orphan
designation threshold. In the EU, an MA for an orphan designated product will not be granted if a similar product has been
approved  in  the  EU  for  the  same  therapeutic  indication,  unless  the  applicant  can  establish  that  (i)  its  product,  although
similar to the orphan medicinal product already authorized is safer, more effective or otherwise clinically superior; (ii) the
MA holder for the orphan medicinal product grants its consent; or (iii) if the MA holder of the orphan medicinal product is
unable to supply sufficient quantities of product. A similar medicine is a product containing a similar active substance or
substances as those contained in an already authorized product. Similar active substance is defined as an identical active
substance, or an active substance with the same principal molecular structural features (but not necessarily all of the same
molecular features) and which acts via the same mechanism.

Post-Brexit, the UK has retained the EU Regulation which governs the designation of medicinal products as orphan
medicinal products and which establishes incentives thereto (Regulation (EC) No. 141/2000) as part of UK law by virtue of
the EU (Withdrawal) Act 2018. However under the Retained EU Law (Revocation and Reform) Bill, which is currently
before the UK Parliament, unless this legislation is expressly preserved and “assimilated” into domestic law or extended by
ministerial regulations (to no later than June 23, 2026) it will automatically expire and be revoked by December 31, 2023.
There is therefore uncertainty about the future regulations relating to orphan designation in Great Britain, and any future
changes to the legal requirements could lead to greater regulatory complexity and increased costs to our business. 

The  MHRA  is  responsible  for  reviewing  applications  from  companies  for  orphan  designation  at  the  time  of  an
MAA.  If  a  medicinal  product  has  been  designated  orphan  in  the  EU  under  Regulation  (EC)  141/2000,  a  Great  Britain
orphan  MAA  can  be  made  under  regulation  50G  of  the  Human  Medicines  Regulation  2012  (as  amended).  A  UK-wide
orphan MAA can only be considered in the absence of an active EU orphan designation. If a UK-wide orphan MA is

62

Table of Contents

granted and the medicinal product subsequently receives EU orphan designation, the MA holder would need to submit a
variation to change this to a Great Britain orphan MA.

We  have  obtained  orphan  drug  designation  from  the  FDA  and  European  Commission  for  AAV-CNGB3  for  the
treatment of achromatopsia caused by mutations in the CNGB3 gene, for AAV-CNGA3 for the treatment of achromatopsia
due to autosomal-recessive CNGA3 gene mutations, for AAV-RPE65 for the treatment of Leber congenital amaurosis, for
botaretigene  sparoparvovec  for  the  treatment  of  X-linked  retinitis  pigmentosa,  for  AAV-AIPL1  for  the  treatment  of
inherited retinal dystrophy due to defects in AIPL1 gene and for AAV-RDH12 for the treatment of retinol dehydrogenase
12  (RDH12)  mutation-associated  retinal  dystrophy,  and  we  obtained  orphan  drug  designation  from  the  FDA  for  AAV-
hAQP1 for the treatment of grade 2 and grade 3 late xerostomia from parotid gland hypofunction caused by radiotherapy.
We may seek orphan drug designation for other current and future product candidates. Even with orphan drug designation,
we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated
with  developing  pharmaceutical  products,  which  could  prevent  us  from  marketing  our  product  candidates  if  another
company  is  able  to  obtain  orphan  drug  exclusivity  before  we  do.  In  addition,  exclusive  marketing  rights  in  the  United
States and the EU may be unavailable if we seek approval for an indication broader than the orphan-designated indication
or may be lost in the United States or EU if the FDA or foreign authorities later determine that the request for designation
was materially defective or if we are unable to assure sufficient quantities of the drug to meet the needs of patients with the
rare disease or condition following approval. Further, even if we obtain orphan drug exclusivity, that exclusivity may not
effectively  protect  our  product  candidates  from  competition  because  different  biologics  with  different  active  principal
molecular  structural  features  can  be  approved  for  the  same  condition.  In  addition,  the  FDA  can  subsequently  approve
products with the same principal molecular structural features, in the case of a biologic, for the same condition if the FDA
concludes that the later product is safer, more effective, or makes a major contribution to patient care. Likewise, in the EU
and  Great  Britain,  the  European  Commission  or  MHRA,  respectively,  can  authorize  a  similar  product  for  the  same
therapeutic indication, if it concludes that the later product is safer, more effective or clinically superior; if the MA holder
for the initial orphan medicinal product grants its consent; or if such MA holder is unable to supply sufficient quantities of
the product. Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives
the  drug  any  advantage  in  the  regulatory  review  or  approval  process.  In  addition,  while  we  intend  to  seek  orphan  drug
designation  for  other  existing  and  future  product  candidates,  we  may  never  receive  such  designations.  There  have  been
legal challenges to aspects of the FDA’s regulations and policies concerning the exclusivity provisions of the Orphan Drug
Act, and future challenges could lead to changes that affect the protections afforded our product candidates in ways that are
difficult to predict. It is uncertain how ongoing and future challenges might affect our business.

We and our contract manufacturers for plasmid are subject to significant regulation with respect to manufacturing our
products. Our manufacturing facilities and the third-party manufacturing facilities which we rely on may not continue
to meet regulatory requirements and have limited capacity.

We currently have relationships with a limited number of suppliers for the manufacturing of plasmid, a component
of  our  viral  vectors  and  product  candidates.  We  completed  the  fit-out  of  our  first  cGMP  manufacturing  facility  in  early
2018  and  we  completed  the  acquisition  of  the  buildings  for  our  second,  large  scale  cGMP  viral  vector  manufacturing
facility  and  our  first  cGMP  plasmid  and  DNA  production  facility  in  Shannon,  Ireland  in  January  2021  to  expand  our
manufacturing  and  supply  chain  capabilities.  However,  if  we  experience  slowdowns  or  problems  with  our  completed
facility  or  the  development  and  completion  of  our  new  facilities  and  are  unable  to  establish  or  scale  our  internal
manufacturing  capabilities,  we  will  need  to  continue  to  contract  with  manufacturers  that  can  produce  the  preclinical,
clinical  and  commercial  supply  of  our  products.  Each  supplier  may  require  licenses  to  manufacture  such  components  if
such processes are not owned by the supplier or in the public domain and we may be unable to transfer or sublicense the
intellectual property rights we may have with respect to such activities.

All entities involved in the preparation of therapeutics for clinical trials or commercial sale, including our existing
contract  manufacturers  for  components  of  our  product  candidates,  are  subject  to  extensive  regulation.  Components  of  a
finished  therapeutic  product  approved  for  commercial  sale  or  used  in  late-stage  clinical  trials  must  be  manufactured  in
accordance with cGMP. These regulations govern manufacturing processes and procedures (including record keeping) and

63

Table of Contents

the  implementation  and  operation  of  quality  systems  to  control  and  assure  the  quality  of  investigational  products  and
products approved for sale. Poor control of production processes can lead to the introduction of adventitious agents or other
contaminants, or to inadvertent changes in the properties or stability of our product candidates that may not be detectable in
final product testing. We or our contract manufacturers must supply all necessary documentation in support of a BLA or
MAA on a timely basis. Our facilities and quality systems and the facilities and quality systems of some or all of our third-
party  contractors  must  pass  a  pre-approval  inspection  for  compliance  with  the  applicable  regulations  as  a  condition  of
regulatory approval of our product candidates or any of our other potential products. In addition, the regulatory authorities
may, at any time, audit or inspect a manufacturing facility involved with the preparation of our product candidates or our
other potential products or the associated quality systems for compliance with the regulations applicable to the activities
being conducted. If these facilities do not pass a pre-approval plant inspection, FDA, MHRA or other regulatory approval
of the products will not be granted.

If  any  such  inspection  or  audit  identifies  a  failure  to  comply  with  applicable  regulations  or  if  a  violation  of  our
product  specifications  or  applicable  regulations  occurs  independent  of  such  an  inspection  or  audit,  we  or  the  relevant
regulatory authority may require remedial measures that may be costly and/or time-consuming for us or a third party to
implement  and  that  may  include  the  temporary  or  permanent  suspension  of  a  clinical  trial  or  commercial  sales  or  the
temporary or permanent closure of a facility. Any such remedial measures imposed upon us or third parties with whom we
contract could harm our business. If we or any of our third-party manufacturers fail to maintain regulatory compliance, the
FDA,  MHRA  or  other  regulatory  authorities  can  impose  regulatory  sanctions  including,  among  other  things,  refusal  to
approve a pending application for a new drug product or biologic product, or revocation of a pre-existing approval. As a
result,  our  business,  financial  condition  and  results  of  operations  may  be  harmed.  Additionally,  if  supply  from  one
approved  manufacturer  is  interrupted,  there  could  be  a  significant  disruption  in  commercial  supply.  An  alternative
manufacturer would need to be qualified through a BLA and/or MAA supplement which could result in further delay. The
regulatory agencies may also require additional studies if a new manufacturer is relied upon for commercial production.
Switching  manufacturers  may  involve  substantial  costs  and  is  likely  to  result  in  a  delay  in  our  desired  clinical  and
commercial timelines.

These  factors  could  cause  the  delay  of  clinical  trials,  regulatory  submissions,  required  approvals  or
commercialization  of  our  product  candidates,  cause  us  to  incur  higher  costs  and  prevent  us  from  commercializing  our
products successfully. Furthermore, if our suppliers fail to meet contractual requirements, and we are unable to secure one
or more replacement suppliers capable of production at a substantially equivalent cost, our clinical trials may be delayed, or
we could lose potential revenue.

Any contamination in our manufacturing process, shortages of raw materials or failure of our plasmid supplier to
deliver necessary components, or other issues with the manufacturing process, could result in delays in our clinical
development or marketing schedules.

Given the nature of biologics manufacturing, there is a risk of contamination. Any contamination could adversely
affect our ability to produce product candidates on schedule and could, therefore, harm our results of operations and cause
reputational damage. Some of the raw materials required in our manufacturing process are derived from biologic sources.
Such raw materials are difficult to procure and may be subject to contamination or recall. In addition, our manufacturing
process is complex, and the manufacturing batch cycle period can be several weeks long. Each batch cycle may not yield
planned  quantities  or  meet  the  required  standards.  A  material  shortage,  contamination,  recall  or  restriction  on  the  use  of
biologically  derived  substances  in  the  manufacture  of  our  product  candidates,  failure  of  manufacturing  equipment  or
systems or other issues with our manufacturing process, could adversely impact or disrupt the commercial manufacturing
or the production of clinical material, which could adversely affect our development timelines and our business, financial
condition, results of operations and prospects.

Expanding our manufacturing capacity has and will continue to be costly and we may be unsuccessful in doing so in a
timely manner, which could delay our current and future clinical development programs, or delay the
commercialization of our product candidates.

In addition to our existing manufacturing facility in London, United Kingdom, we may lease, operate, purchase, or
construct additional facilities to conduct expanded manufacturing or other related activities in the future. In January 2021,
we  completed  the  acquisition  of  our  second,  large  scale  cGMP  viral  vector  manufacturing  facility  and  our  first  cGMP
plasmid  and  DNA  production  facility  in  Shannon,  Ireland.  Expanding  our  manufacturing  capacity  to  produce  the
preclinical, clinical and commercial supply of our products and their components will require completing our new facilities
in  Ireland,  substantial  additional  expenditures,  time,  and  various  regulatory  approvals  and  permits,  all  of  which  may  be
impacted  by  the  COVID-19  pandemic.  Further,  we  will  need  to  hire  and  train  significant  numbers  of  employees  and
managerial personnel to staff our expanding manufacturing and supply chain operations, including in our new facilities in
Ireland.  Start-up  costs  can  be  large  and  may  exceed  our  expectations,  and  scale-up  entails  significant  risks  related  to
process development and manufacturing yields. In addition, we may face difficulties or delays in developing or acquiring
the necessary production equipment and technology to manufacture sufficient quantities of our product candidates for use
in clinical trials and, should they be approved, to supply the commercial market at reasonable costs and in compliance with
applicable regulatory requirements. We may not successfully expand or establish sufficient manufacturing capabilities or
manufacture our products economically or in compliance with cGMP and other regulatory requirements, and we and our
collaborators may not be able to build or procure additional capacity in the required timeframe to meet the requirements of
our clinical programs or to meet potential commercial demand for our product candidates. This could also delay or require
us  to  discontinue  one  or  more  of  our  clinical  development  programs  or  could  interfere  with  our  efforts  to  successfully
commercialize  our  products.  As  a  result,  our  business,  prospects,  operating  results,  and  financial  condition  could  be
materially harmed.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed
or otherwise adversely affected.

The  timely  completion  of  clinical  trials  in  accordance  with  their  protocols  depends,  among  other  things,  on  our
ability to enroll a sufficient number of patients who remain in the study until its conclusion. The natural history studies may
fail to provide us with patients for our clinical trials because patients enrolled in the natural history studies may not be good
candidates for our clinical trials or may choose to not enroll in our clinical trials. We may encounter delays in enrolling, or
be unable to enroll, a sufficient number of patients to complete any of our clinical trials, and even once enrolled we may be
unable to retain a sufficient number of patients to complete any of our trials. This may result in increased costs, program
delays or both, which could have a harmful effect on our ability to develop our product candidates, or could render further
development impossible. The enrollment of patients depends on many factors, including:

● the size and nature of the patient population;

● the patient eligibility criteria defined in the protocol;

● the size of the patient population required for analysis of the trial’s primary endpoints;

● the proximity of patients to study sites;

● the design of the trial or side effects that may arise in development;

● our ability to recruit clinical trial investigators with the appropriate competencies and experience;

65

Table of Contents

● clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied
in  relation  to  other  available  therapies,  including  any  new  products  that  may  be  approved  for  the
indications we are investigating;

● our ability to obtain and maintain patient consents;

● the risk that patients enrolled in clinical trials will drop out of the trials before completion; and

● business  interruptions  resulting  from  geopolitical  actions,  including  war  and  terrorism,  or  widespread
health  emergencies,  such  as  the  COVID-19  pandemic,  or  natural  disasters  including  earthquakes,
typhoons, floods and fires, or from economic or political instability.

In  addition,  other  clinical  trials  for  product  candidates  that  are  in  the  same  therapeutic  areas  as  our  product
candidates or approved products for the same clinical indications (such as Luxturna marketed by Spark Therapeutics, Inc.
for the treatment of RPE65-associated retinal disease) may reduce the number and type of patients available to us.

Our product candidates may cause serious adverse events or undesirable side effects or have other properties which may
delay or prevent their regulatory approval, limit the commercial profile of an approved label, or, result in significant
negative consequences following marketing approval, if any.

Serious adverse events or undesirable side effects caused by our product candidates could cause us or regulatory
authorities  to  interrupt,  delay  or  halt  clinical  trials  and  could  result  in  a  more  restrictive  label  or  the  delay  or  denial  of
regulatory  approval  by  the  FDA,  MHRA  or  other  authorities.  Results  of  our  clinical  trials  could  reveal  a  high  and
unacceptable severity and prevalence of side effects, toxicities or unexpected characteristics, including death. A risk in any
gene therapy product based on viral vectors is the risk of insertional mutagenesis.

If unacceptable side effects or deaths arise in the development of our product candidates, we, the FDA, the IRBs at
the  institutions  in  which  our  studies  are  conducted,  DSMB,  or  other  regulatory  bodies  could  suspend  or  terminate  our
clinical trials or the FDA, MHRA or other regulatory authorities could order us to cease clinical trials or deny approval of
our  product  candidates  for  any  or  all  targeted  indications.  Undesirable  side  effects  or  deaths  in  clinical  trials  with  our
product  candidates  may  cause  the  FDA  or  comparable  foreign  regulatory  authorities  to  place  a  clinical  hold  on  the
associated clinical trials, to require additional studies, or otherwise to delay or deny approval of our product candidates for
any or all targeted indications. Treatment-related side effects could also affect patient recruitment or the ability of enrolled
patients  to  complete  the  trial  or  result  in  potential  product  liability  claims.  In  addition,  these  side  effects  may  not  be
appropriately recognized or managed by the treating medical staff. We expect to have to train medical personnel using our
product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of
our product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates
could result in patient injury or death. Any of these occurrences may harm our business, financial condition and prospects
significantly.

If  any  of  our  product  candidates  receives  marketing  approval,  and  we  or  others  later  identify  undesirable  side
effects caused by any such product, including during any long-term follow-up observation period recommended or required
for  patients  who  receive  treatment  using  our  products,  a  number  of  potentially  significant  negative  consequences  could
result, including:

● regulatory authorities may withdraw approvals of such product;

● we may be required to recall a product or change the way such product is administered to patients;

66

Table of Contents

● additional restrictions may be imposed on the marketing of the particular product or the manufacturing

processes for the product;

● regulatory authorities may require additional warnings on the label, such as a “black box” warning or

contraindication;

● we may be required to implement a Risk Evaluation and Mitigation Strategy, or REMS, or create a

medication guide outlining the risks of such side effects for distribution to patients or similar risk
management measures;

● the product could become less competitive;

● we could be sued and held liable for harm caused to patients; and

● our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product

candidate, if approved, and could significantly harm our business, results of operations and prospects.

Success in preclinical studies or clinical trials may not be indicative of results in future clinical trials.

Results  from  previous  preclinical  studies  or  clinical  trials  are  not  necessarily  predictive  of  future  clinical  trial
results, and interim results of a clinical trial are not necessarily indicative of final results. Our product candidates may fail
to  show  the  desired  safety  and  efficacy  in  clinical  development  despite  positive  results  in  preclinical  studies  or  having
successfully advanced through initial clinical trials.

Success  in  preclinical  testing  and  early  clinical  trials  does  not  ensure  that  later  clinical  trials  will  generate  the

same results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate.

Frequently,  product  candidates  that  have  shown  promising  results  in  early  clinical  trials  have  subsequently
suffered  significant  setbacks  in  later  clinical  trials.  In  addition,  the  design  of  a  clinical  trial  can  determine  whether  its
results will support approval of a product and flaws in the design of a clinical trial may not become apparent until the
clinical  trial  is  well  advanced.  We  have  limited  experience  designing  clinical  trials  and  may  be  unable  to  design  and
execute  a  clinical  trial  to  support  regulatory  approval.  There  is  a  high  failure  rate  for  drugs  and  biologic  products
proceeding  through  clinical  trials.  Data  obtained  from  preclinical  and  clinical  activities  are  subject  to  varying
interpretations,  which  may  delay,  limit  or  prevent  regulatory  approval,  which  could  negatively  impact  our  business,
financial condition, results of operations and prospects.

The regulatory approval processes of the FDA, MHRA, competent authorities in the EU and other regulatory
authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain
regulatory approval for our product candidates, our business will be substantially harmed.

The time required to obtain approval by the FDA, MHRA, European Commission and other regulatory authorities
is  unpredictable  but  typically  takes  many  years  following  the  commencement  of  clinical  trials  and  depends  upon
numerous  factors,  including  the  substantial  discretion  of  the  regulatory  authorities.  In  addition,  approval  policies,
regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product
candidate’s  clinical  development  and  may  vary  among  jurisdictions.  For  instance,  the  EU  pharmaceutical  legislation  is
currently  undergoing  a  complete  review  process,  in  the  context  of  the  Pharmaceutical  Strategy  for  Europe  initiative,
launched by the European Commission in November 2020. The European Commission’s proposal for revision of several
legislative instruments related to medicinal products (potentially revising the duration of regulatory exclusivity, eligibility
for expedited pathways, etc.) is currently expected during the first quarter of 2023. The proposed revisions,

67

Table of Contents

once they are agreed and adopted by the European Parliament and European Council (not expected before the end of 2024
or early 2025) may have a significant impact on the pharmaceutical industry in the long term.

We have not obtained regulatory approval for any product candidate and it is possible that none of our product
candidates  in  clinical  programs  or  any  other  product  candidates  we  may  seek  to  develop  in  the  future  will  ever  obtain
regulatory approval. Neither we nor any future collaborator is permitted to market any of our product candidates in the
United States, the UK or the EU until we receive regulatory approval of a BLA from the FDA or of an MAA from the
MHRA or European Commission, respectively. It is possible that the FDA may refuse to accept for substantive review
any BLAs, or the MHRA or EMA any of our MAAs, that we submit for our product candidates or may conclude after
review of our data that our application is insufficient to obtain marketing approval of our product candidates.

Prior  to  obtaining  approval  to  commercialize  a  product  candidate  in  the  United  States,  the  UK,  the  EU  or
elsewhere, we or our collaborators must demonstrate with substantial evidence from well-controlled clinical trials, and to
the  satisfaction  of  the  FDA,  MHRA,  EMA  or  foreign  regulatory  agencies,  that  such  product  candidates  are  safe  and
effective for their intended uses. Results from nonclinical studies and clinical trials can be interpreted in different ways.
Even  if  we  believe  the  nonclinical  or  clinical  data  for  our  product  candidates  are  promising,  such  data  may  not  be
sufficient  to  support  approval  by  the  FDA,  MHRA,  European  Commission  or  other  regulatory  authorities.  The  FDA,
MHRA or EMA may also require us to conduct additional preclinical studies or clinical trials for our product candidates
either  prior  to  or  post-approval,  or  it  may  object  to  elements  of  our  clinical  development  program.  Depending  on  the
extent of these or any other FDA, MHRA or EMA required studies, approval of any regulatory approval applications that
we  submit  may  be  delayed  by  several  years,  or  may  require  us  to  expend  significantly  more  resources  than  we  have
available.

Of  the  large  number  of  potential  products  in  development,  only  a  small  percentage  successfully  complete  the
FDA, MHRA, or other foreign regulatory approval processes and are commercialized. The lengthy approval process as
well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market
our product candidates, which would significantly harm our business, results of operations and prospects.

Even if we and / or our collaboration partners, as applicable, obtain FDA, MHRA or European Commission
approval for AAV-GAD, botaretigene sparoparvovec, AAV-CNGB3, AAV-CNGA3, AAV-RPE65, AAV-hAQP1 or our
other product candidates in the United States, UK or EU, we may never obtain approval for or commercialize them in
any other jurisdiction, which would limit our ability to realize their full market potential.

In order to market any products in any particular jurisdiction, we must establish and comply with numerous and
varying regulatory requirements on a country-by-country basis regarding safety and efficacy. Approval by the FDA in the
United States, the MHRA in Great Britain or the competent authorities in the EU does not ensure approval by regulatory
authorities in other countries or jurisdictions. However, the failure to obtain approval in one jurisdiction may negatively
impact our ability to obtain approval elsewhere. In addition, clinical trials conducted in one country may not be accepted
by  regulatory  authorities  in  other  countries,  and  regulatory  approval  in  one  country  does  not  guarantee  regulatory
approval in any other country.

Approval processes vary among countries and can involve additional product testing and validation and additional
administrative review periods. Seeking foreign regulatory approval could result in difficulties and increased costs for us
and  require  additional  preclinical  studies  or  clinical  trials  which  could  be  costly  and  time  consuming.  Regulatory
requirements  can  vary  widely  from  country  to  country  and  could  delay  or  prevent  the  introduction  of  our  products  in
those countries. We do not have any product candidates approved for sale in any jurisdiction, including in international
markets, and we do not have experience in obtaining regulatory approval in international markets. If we fail to comply
with  regulatory  requirements  in  international  markets  or  to  obtain  and  maintain  required  approvals,  or  if  regulatory
approvals in international markets are delayed, our target market will be reduced and our ability to realize the full market
potential of any product we develop will be unrealized.

68

Table of Contents

Even if we receive regulatory approval of one or more of our product candidates, we will be subject to ongoing
regulatory obligations and continued regulatory review, which may result in significant additional expense, and we may
be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our
product candidates.

Any  product  candidate  for  which  we  obtain  marketing  approval,  along  with  the  manufacturing  processes,  post-
approval clinical data, labeling, packaging, distribution, adverse event reporting, storage, recordkeeping, export, import,
advertising  and  promotional  activities  for  such  product,  among  other  things,  will  be  subject  to  extensive  and  ongoing
requirements  of  and  review  by  the  FDA,  MHRA  and  other  regulatory  authorities.  These  requirements  include
submissions  of  safety  and  other  post-marketing  information  and  reports,  establishment  registration  and  drug  listing
requirements,  continued  compliance  with  cGMP  and  similar  requirements  relating  to  manufacturing,  quality  control,
quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of
samples to physicians and recordkeeping and GCP requirements for any clinical trials that we conduct post-approval.

The FDA, MHRA and other regulatory authorities closely regulate the post-approval marketing and promotion of
genetic  therapy  medicines  to  ensure  they  are  marketed  only  for  the  approved  indications  and  in  accordance  with  the
provisions of the approved labeling. The FDA, MHRA and other regulatory authorities impose stringent restrictions on
manufacturers’  communications  regarding  off-label  use  and  if  we  market  our  products  for  uses  beyond  their  approved
indications, we may be subject to enforcement action for off-label marketing. Violations of the U.S. federal Food, Drug,
and Cosmetic Act, or FDCA, relating to the promotion of prescription drugs may lead to FDA enforcement actions and
investigations  alleging  violations  of  federal  and  state  health  care  fraud  and  abuse  laws,  as  well  as  state  consumer
protection laws. Similar risks apply in foreign jurisdictions.  

In  addition,  later  discovery  of  previously  unknown  adverse  events  or  other  problems  with  our  products,
manufacturers or manufacturing processes, including adverse events of unanticipated severity or frequency, or with our
manufacturing  processes  or  third-party  manufacturers,  or  failure  to  comply  with  regulatory  requirements,  may  yield
various results, including:

● restrictions on manufacturing such products;

● restrictions on the labeling or marketing of a product;

● restrictions on product distribution or use;

● requirements to conduct post-marketing studies or clinical trials;

● warning letters or holds on clinical trials;

● withdrawal of the products from the market;

● refusal to approve pending applications or supplements to approved applications that we submit;

● recall of products;

● fines, restitution or disgorgement of profits or revenues;

● suspension or withdrawal of marketing approvals;

● refusal to permit the import or export of our products;

● product seizure or detention; or

69

Table of Contents

● injunctions or the imposition of civil or criminal penalties.

The FDA’s and foreign regulatory authorities’ policies may change and additional government regulations may be
enacted  that  could  prevent,  limit  or  delay  regulatory  approval  of  our  product  candidates.  We  also  cannot  predict  the
likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either
in the United States or in other countries. If we are slow or unable to adapt to changes in existing requirements or the
adoption  of  new  requirements  or  policies,  or  if  we  are  not  able  to  maintain  regulatory  compliance,  we  may  lose  any
marketing  approval  that  we  may  have  obtained  which  would  adversely  affect  our  business,  prospects  and  ability  to
achieve or sustain profitability.

Interim, “topline” and preliminary data from our clinical trials that we announce or publish from time to time may
change as more patient data become available and are subject to audit and verification procedures that could result
in material changes in the final data.

From time to time, we may publicly disclose preliminary or topline data from our clinical trials, which is based on
a  preliminary  analysis  of  then-available  data,  and  the  results  and  related  findings  and  conclusions  are  subject  to  change
following  a  more  comprehensive  review  of  the  data  related  to  the  particular  study  or  trial.  We  also  make  assumptions,
estimations,  calculations  and  conclusions  as  part  of  our  analyses  of  data,  and  we  may  not  have  received  or  had  the
opportunity to fully and carefully evaluate all data. As a result, the topline or preliminary results that we report may differ
from future results of the same studies, or different conclusions or considerations may qualify such results, once additional
data  have  been  received  and  fully  evaluated.  Topline  and  preliminary  data  also  remain  subject  to  audit  and  verification
procedures that may result in the final data being materially different from the topline or preliminary data we previously
published. As a result, topline and preliminary data should be viewed with caution until the final data are available.

 From time to time, we may also disclose interim data from our clinical trials. Interim data from these trials that
we  may  complete  are  subject  to  the  risk  that  one  or  more  of  the  clinical  outcomes  may  materially  change  as  subject
enrollment continues and more data become available. Adverse differences between interim data and topline, preliminary,
or final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors
could result in volatility in the price of our ordinary shares.

  Further,  others,  including  regulatory  agencies,  may  not  accept  or  agree  with  our  assumptions,  estimates,
calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the
value of the particular program, the approvability or commercialization of the particular product candidate or product and
our company in general. In addition, the information we choose to publicly disclose regarding a particular clinical trial is
based on what is typically extensive information, and you or others may not agree with what we determine is material or
otherwise appropriate information to include in our disclosure. If the interim, topline, or preliminary data that we report
differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability
to  obtain  approval  for,  and  commercialize,  our  product  candidates  may  be  harmed,  which  could  harm  our  business,
operating results, prospects or financial condition.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize
on product candidates or indications that may be more profitable or for which there is a greater likelihood of
success.

Because  we  have  limited  financial  and  managerial  resources,  we  focus  on  research  programs  and  product
candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other
product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation
decisions may cause us to fail to timely capitalize on viable commercial products or profitable market opportunities. Our
spending on current and future research and development programs and product candidates for specific indications may
not yield any commercially viable products. If we do not accurately evaluate the commercial potential

70

Table of Contents

or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through
collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to
retain sole development and commercialization rights to such product candidate.

Changes in funding for, or disruptions caused by global health concerns impacting, the FDA and other government
or regulatory agencies could hinder their ability to hire and retain key leadership and other personnel, or otherwise
prevent new products and services from being developed, approved or commercialized in a timely manner, which
could negatively impact our business.

The ability of the FDA and foreign regulatory authorities to review and approve new products can be affected by a
variety of factors, including government budget and funding levels, disruptions caused by global health concerns such as
the COVID-19 pandemic, ability to hire and retain key personnel, including those with experience relating to novel gene
therapy product candidates, acceptance of the payment of user fees, statutory, regulatory, and policy changes and other
events that may otherwise affect the FDA’s or foreign regulatory authorities’ ability to perform routine functions. Average
review  times  at  the  FDA  and  foreign  regulatory  authorities  have  fluctuated  in  recent  years  as  a  result.  In  addition,
government funding of other government agencies that fund research and development activities is subject to the political
process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other government or regulatory agencies such as the EMA, following its relocation to
Amsterdam  and  related  reorganization  (including  staff  changes),  may  also  slow  the  time  necessary  for  new  product
candidates to be reviewed and/or approved, which would adversely affect our business. For example, over the last several
years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to
furlough critical FDA employees and stop critical activities.

Risks Related to Healthcare Laws and Other Legal Compliance Matters

Enacted and future healthcare legislation may increase the difficulty and cost for us to obtain marketing approval
of and commercialize our product candidates and may affect the prices we may set.

In the United States, the UK, the EU and other jurisdictions, there have been, and we expect there will continue to
be, a number of legislative and regulatory changes and proposed changes to the healthcare system that could affect our
future results of operations. In particular, there have been and continue to be a number of initiatives at the U.S. federal
and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010,
the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education  Reconciliation  Act,  or
collectively the ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and
private insurers. Among the provisions of the ACA, those of greatest importance to the pharmaceutical and biotechnology
industries include the following:

● an  annual,  non-deductible  fee  payable  by  any  entity  that  manufactures  or  imports  certain  branded
prescription  drugs  and  biologic  agents  (other  than  those  designated  as  orphan  drugs),  which  is
apportioned  among  these  entities  according  to  their  market  share  in  certain  government  healthcare
programs;

● a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program

are calculated for drugs that are inhaled, infused, instilled, implanted or injected;

● expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer
Medicaid  coverage  to  certain  individuals  with  income  at  or  below  133%  of  the  federal  poverty  level,
thereby potentially increasing a manufacturer’s Medicaid rebate liability;

● a licensure framework for follow on biologic products;

71

Table of Contents

● a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct

comparative clinical effectiveness research, along with funding for such research; and

● establishment of a Center for Medicare & Medicaid Innovation at the Centers for Medicare & Medicaid
Services,  or  CMS,  to  test  innovative  payment  and  service  delivery  models  to  lower  Medicare  and
Medicaid spending, potentially including prescription drug spending.

Since its enactment, there have been judicial, Congressional and executive branch challenges to certain aspects of
the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by
several  states  without  specifically  ruling  on  the  constitutionality  of  the  ACA.  Prior  to  the  Supreme  Court’s  decision,
President  Biden  issued  an  executive  order  to  initiate  a  special  enrollment  period  for  purposes  of  obtaining  health
insurance coverage through the ACA marketplace from February 15, 2021 through August 15, 2021. The executive order
also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to
healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work
requirements,  and  policies  that  create  unnecessary  barriers  to  obtaining  access  to  health  insurance  coverage  through
Medicaid or the ACA.

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  in  the  United  States  since  the  ACA  was
enacted. In August 2011, the Budget Control Act of 2011, among other things, led to aggregate reductions of Medicare
payments  to  providers  of  2%  per  fiscal  year.  These  reductions  went  into  effect  in  April  2013  and,  due  to  subsequent
legislative amendments to the statute, will remain in effect through 2030, with the exception of a temporary suspension
from May 1, 2020 through March 31, 2022. Under current legislation, the actual reduction in Medicare payment varies
from 1% from April 1, 2022 through June 30, 2022, to up to 3% in the final year of this sequester, unless additional action
is taken by Congress. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among
other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and
cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to
providers  from  three  to  five  years.  These  new  laws  or  any  other  similar  laws  introduced  in  the  future  may  result  in
additional  reductions  in  Medicare  and  other  health  care  funding,  which  could  negatively  affect  our  customers  and
accordingly, our financial operations.

Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives.
For  example,  CMS  may  develop  new  payment  and  delivery  models,  such  as  bundled  payment  models.  In  addition,
recently  there  has  been  heightened  governmental  scrutiny  over  the  manner  in  which  manufacturers  set  prices  for  their
marketed  products,  which  has  resulted  in  several  U.S.  Congressional  inquiries  and  proposed  and  enacted  federal
legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs
under  Medicare,  and  review  the  relationship  between  pricing  and  manufacturer  patient  programs.  We  expect  that
additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts
that the U.S. federal government will pay for healthcare products and services, which could result in reduced demand for
our product candidates or additional pricing pressures.

Individual  states  in  the  United  States  have  also  increasingly  passed  legislation  and  implemented  regulations
designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints,
discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some
cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on
payment  amounts  by  third-party  payors  or  other  restrictions  could  harm  our  business,  results  of  operations,  financial
condition  and  prospects.  In  addition,  regional  healthcare  authorities  and  individual  hospitals  are  increasingly  using
bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription
drug and other healthcare programs. This could reduce the ultimate demand for our product candidates or put pressure on
our product pricing.

72

Table of Contents

In  addition,  FDA  regulations  and  guidance  may  be  revised  or  reinterpreted  by  the  FDA  in  ways  that  may
significantly affect our business and our products. Any new regulations or guidance, or revisions or reinterpretations of
existing regulations or guidance, may impose additional costs or lengthen FDA review times for our product candidates.
We  cannot  determine  how  changes  in  regulations,  statutes,  policies,  or  interpretations  when  and  if  issued,  enacted  or
adopted, may affect our business in the future.

Such  changes  would  likely  require  substantial  time  and  impose  significant  costs,  or  could  reduce  the  potential
commercial value of our product candidates, and could materially harm our business and our financial results. In addition,
delays  in  receipt  of  or  failure  to  receive  regulatory  clearances  or  approvals  for  any  other  products  would  harm  our
business, financial condition, and results of operations.

In the UK and EU, similar political, economic and regulatory developments may affect our ability to profitably
commercialize  our  product  candidates,  if  approved.  In  addition  to  continuing  pressure  on  prices  and  cost  containment
measures,  legislative  developments  at  the  UK  or  the  EU  or  member  state  level  may  result  in  significant  additional
requirements  or  obstacles  that  may  increase  our  operating  costs.  The  delivery  of  healthcare  in  the  UK  and  the  EU,
including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost
exclusively  a  matter  for  national  law  and  policy.  National  governments  and  health  service  providers  have  different
priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that context. In
general,  however,  the  healthcare  budgetary  constraints  in  the  UK  and  in  most  EU  member  states  have  resulted  in
restrictions  on  the  pricing  and  reimbursement  of  medicines  by  relevant  health  service  providers.  Coupled  with  ever-
increasing  national  regulatory  burdens  on  those  wishing  to  develop  and  market  products,  this  could  prevent  or  delay
marketing  approval  of  our  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to
commercialize our product candidates, if approved.

In markets outside of the United States, the UK and the EU, reimbursement and healthcare payment systems vary

significantly by country, and many countries have instituted price ceilings on specific products and therapies.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation
or administrative action in the United States, the UK the EU or any other jurisdiction. If we or any third parties we may
engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or
if we or such third parties are not able to maintain regulatory compliance, our product candidates may lose any regulatory
approval that may have been obtained and we may not achieve or sustain profitability.

Our  business  operations  and  current  and  future  relationships  with  investigators,  healthcare  professionals,
consultants,  third-party  payors,  patient  organizations  and  customers  will  be  subject  to  applicable  healthcare
regulatory laws, which could expose us to penalties.

Our  business  operations  and  current  and  future  arrangements  with  investigators,  healthcare  professionals,
consultants, third-party payors, patient organizations and customers, may expose us to broadly applicable fraud and abuse
laws  and  other  healthcare  laws  and  regulations.  These  laws  may  constrain  the  business  or  financial  arrangements  and
relationships  through  which  we  conduct  our  operations,  including  how  we  research,  market,  sell  and  distribute  our
product candidates, if approved. Such laws include:

● the  U.S.  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  or  entities  from
knowingly  and  willfully  soliciting,  offering,  receiving  or  providing  any  remuneration  (including  any
kickback, bribe, or certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce
or  reward,  or  in  return  for,  either  the  referral  of  an  individual  for,  or  the  purchase,  lease,  order  or
recommendation of, any good, facility, item or service, for which payment may be made, in whole or in
part,  under  U.S.  federal  and  state  healthcare  programs  such  as  Medicare  and  Medicaid.  A  person  or
entity does not need to have actual knowledge of the statute or specific intent to violate it in order to
have committed a violation;

73

Table of Contents

● the  U.S.  federal  civil  and  criminal  false  claims  and  civil  monetary  penalties  laws,  including  the  civil
False  Claims  Act,  which,  among  other  things,  impose  criminal  and  civil  penalties,  including  through
civil  whistleblower  or  qui  tam  actions,  against  individuals  or  entities  for  knowingly  presenting,  or
causing to be presented, to the U.S. federal government, claims for payment or approval that are false or
fraudulent, knowingly making, using or causing to be made or used, a false record or statement material
to a false or fraudulent claim, or from knowingly making a false statement to avoid, decrease or conceal
an obligation to pay money to the U.S. federal government. In addition, the government may assert that
a claim including items and services resulting from a violation of the U.S. federal Anti-Kickback Statute
constitutes a false or fraudulent claim for purposes of the False Claims Act;

● the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created
additional  federal  criminal  statutes  which  prohibit,  among  other  things,  knowingly  and  willfully
executing, or attempting to execute, a scheme to defraud any healthcare benefit program, or knowingly
and  willfully  falsifying,  concealing  or  covering  up  a  material  fact  or  making  any  materially  false
statement,  in  connection  with  the  delivery  of,  or  payment  for,  healthcare  benefits,  items  or  services.
Similar  to  the  U.S.  federal  Anti-Kickback  Statute,  a  person  or  entity  does  not  need  to  have  actual
knowledge of the statute or specific intent to violate it in order to have committed a violation;

● the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and

medical devices;

● the U.S. Public Health Service Act, which prohibits, among other things, the introduction into interstate

commerce of a biological product unless a biologics license is in effect for that product;

● federal consumer protection and unfair competition laws, which broadly regulate marketplace activities

and activities that potentially harm consumers;

● the  U.S.  Physician  Payments  Sunshine  Act  and  its  implementing  regulations,  which  requires  certain
manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare,
Medicaid,  or  the  Children’s  Health  Insurance  Program,  with  specific  exceptions,  to  report  annually  to
the  government  information  related  to  certain  payments  and  other  transfers  of  value  to  physicians
(defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain non-physician
practitioners  (physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  nurse
anesthetists, anesthesiologist assistants and certified nurse midwives), and teaching hospitals, as well as
ownership and investment interests held by physicians and their immediate family members;

● analogous U.S. state laws and regulations, including: state anti-kickback and false claims laws, which
may  apply  to  our  business  practices,  including  but  not  limited  to,  research,  distribution,  sales  and
marketing arrangements and claims involving healthcare items or services reimbursed by any third-party
payor, including private insurers; state laws that require pharmaceutical companies to comply with the
pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance  guidance
promulgated  by  the  U.S.  federal  government,  or  otherwise  restrict  payments  that  may  be  made  to
healthcare  providers  and  other  potential  referral  sources;  state  laws  and  regulations  that  require  drug
manufacturers to file reports relating to pricing and marketing information, which requires tracking gifts
and other remuneration and items of value provided to healthcare professionals and entities; and state
and local laws that require the registration of pharmaceutical sales representatives; and

● similar healthcare laws and regulations in the UK, EU and other jurisdictions, including reporting

requirements detailing interactions with and payments to healthcare providers.

Ensuring  that  our  internal  operations  and  future  business  arrangements  with  third  parties  comply  with  applicable
healthcare  laws  and  regulations  will  involve  substantial  costs.  It  is  possible  that  governmental  authorities  will  conclude
that  our  business  practices  do  not  comply  with  current  or  future  statutes,  regulations,  agency  guidance  or  case  law
involving  applicable  fraud  and  abuse  or  other  healthcare  laws  and  regulations.  If  our  operations  are  found  to  be  in
violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may
be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from
government-funded  healthcare  programs,  such  as  Medicare  and  Medicaid  or  similar  programs  in  other  countries  or
jurisdictions,  integrity  oversight  and  reporting  obligations  to  resolve  allegations  of  non-compliance,  disgorgement,
individual imprisonment, contractual damages, reputational harm, diminished profits and the curtailment or restructuring
of our operations. If any of the physicians or other providers or entities with whom we expect to do business are found to
not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including
exclusions from government funded healthcare programs and imprisonment, which could affect our ability to operate our
business. Further, defending against any such actions can be costly, time-consuming and may require significant personnel
resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our
business may be impaired.

We are subject to regulation and other legal obligations relating to privacy and data protection. Compliance with these
requirements is complex and costly. Failure to comply could materially harm our business.

The global data protection landscape is rapidly evolving, and we are or may become subject to numerous state,
federal and foreign laws, requirements and regulations governing the collection, use, disclosure, retention and security of
personal information.

In  the  U.S.,  HIPAA  imposes  privacy,  security  and  breach  reporting  obligations  with  respect  to  individually
identifiable health information upon “covered entities” (health plans, health care clearinghouses and certain health care
providers),  and  their  respective  business  associates,  individuals  or  entities  that  create,  receive,  maintain  or  transmit
protected health information in connection with providing a service for or on behalf of a covered entity, as well as their
covered subcontractors. Most healthcare providers, including research institutions and other vendors from which we may
obtain patient health information, are subject to privacy and security regulations promulgated under HIPAA. We do not
believe  that  we  are  currently  acting  as  a  covered  entity  or  business  associate  under  HIPAA  and  thus  are  not  directly
subject  to  its  requirements  or  penalties.  However,  depending  on  the  facts  and  circumstances,  we  could  face  substantial
criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered healthcare
provider  or  research  institution  that  has  not  satisfied  HIPAA’s  requirements  for  disclosure  of  individually  identifiable
health information.  

In addition, certain state laws govern the privacy and security of health information in certain circumstances, some
of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have
the same effect, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in
the imposition of significant civil and/or criminal penalties and private litigation. Further, we may also be subject to other
state  laws  governing  the  privacy,  processing  and  protection  of  personal  information.  For  example,  the  California
Consumer Privacy Act, or CCPA, confers individual privacy rights for California consumers (as such term is defined in
the law) and places increased privacy and security obligations on entities handling personal information of consumers or
households. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that
has  increased  the  likelihood  of,  and  risks  associated  with,  data  breach  litigation.  Further,  the  California  Privacy  Rights
Act, or the CPRA, generally went into effect in January 2023, and significantly amends the CCPA and imposes additional
data  protection  obligations  on  covered  businesses,  including  additional  consumer  rights  processes,  limitations  on  data
uses,  new  audit  requirements  for  higher  risk  data,  and  opt  outs  for  certain  uses  of  sensitive  data.  It  also  created  a  new
California  data  protection  agency  authorized  to  issue  substantive  regulations  and  could  result  in  increased  privacy  and
information  security  enforcement.  Additional  compliance  investment  and  potential  business  process  changes  may  be
required. The CCPA, the CPRA and other domestic privacy and data protection laws and regulations may increase our
compliance costs and potential liability.

75

Our operations abroad may also be subject to increased scrutiny or attention from data protection authorities. For
example, the GDPR imposes stringent requirements for processing the personal data of individuals within the European
Economic Area, or EEA, which consists of the 27 EU member states plus Norway, Lichtenstein and Iceland. Companies
that  must  comply  with  the  GDPR  face  increased  compliance  obligations  and  risk,  including  more  robust  regulatory
enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or up to 4% of
the total worldwide annual turnover of the relevant undertaking in the preceding financial year, whichever is higher, and
other administrative penalties.  

Among other requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries
that have not been found to provide adequate protection to such personal data, including the U.S. In July 2020, the Court of
Justice of the European Union, or CJEU, limited how organizations could lawfully transfer personal data from the EEA to
the U.S. by invalidating the Privacy Shield for purposes of international transfers and imposing further restrictions on the
use  of  standard  contractual  clauses  (a  standard  form  of  contract  approved  by  the  European  Commission  as  an  adequate
personal data transfer mechanism, and potential alternative to the Privacy Shield), or SCCs. In March 2022, the U.S. and
EU announced a new regulatory regime intended to replace the invalidated regulations; however, this new EU-U.S. Data
Privacy Framework has not been implemented beyond an executive order signed by President Biden on October 7, 2022 on
Enhancing  Safeguards  for  United  States  Signals  Intelligence  Activities.  European  court  and  regulatory  decisions
subsequent  to  the  CJEU  decision  of  July  2020  have  taken  a  restrictive  approach  to  international  data  transfers.  As
supervisory  authorities  issue  further  guidance  on  personal  data  export  mechanisms,  including  circumstances  where  the
SCCs cannot be used, and/or start taking enforcement action, we could suffer additional costs, complaints and/or regulatory
investigations  or  fines.  If,  owing  to  the  restriction  or  perceived  restriction  of  personal  data  transfers,  we  are  otherwise
unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner
in  which  we  provide  our  services,  the  geographical  location  or  segregation  of  our  relevant  systems  and  operations,  and
could adversely affect our financial results.

Further, we are subject to the UK data protection regime, which imposes separate but similar obligations to those
under  the  GDPR  and  comparable  penalties,  including  fines  of  up  to  £17.5  million  or  4%  of  a  noncompliant  company’s
global annual revenue for the preceding financial year, whichever is greater. As we continue to expand into other foreign
countries and jurisdictions, we may be subject to additional laws and regulations that may affect how we conduct business.

Although  we  work  to  comply  with  applicable  laws,  regulations  and  standards,  as  well  as  our  contractual
obligations and other legal obligations, relating to data privacy and security, these requirements are evolving and may be
modified, interpreted and applied in an inconsistent manner from one jurisdiction and/or organization to another, and may
conflict with one another or other legal obligations with which we must comply. Any failure or perceived failure by us or
our  employees,  representatives,  contractors,  consultants,  collaborators,  or  other  third  parties  to  comply  with  such
requirements or adequately address privacy and security concerns, even if unfounded, could result in additional cost and
liability to us, damage our reputation, and adversely affect our business and results of operations.

We are subject to environmental, health and safety laws and regulations, and we may become exposed to liability
and substantial expenses in connection with environmental compliance or remediation activities.

Our  operations,  including  our  development,  testing  and  manufacturing  activities,  are  subject  to  numerous
environmental,  health  and  safety  laws  and  regulations.  These  laws  and  regulations  govern,  among  other  things,  the
controlled use, handling, release and disposal of and the maintenance of a registry for, hazardous materials and biological
materials, such as chemical solvents, human cells, carcinogenic compounds, mutagenic compounds and compounds that
have a toxic effect on reproduction, laboratory procedures and exposure to blood-borne pathogens. If we fail to comply
with such laws and regulations, we could be subject to fines or other sanctions. Additionally, if environmental regulations
are  enacted  that  restrict  our  ability  to  use  one  or  more  of  the  materials  or  compounds  necessary  to  manufacture  our
product candidates, and we are unable to find suitable alternatives or such alternatives require additional testing or will

76

Table of Contents

extend the manufacturing timeline, then we may be unable to manufacture our product candidates in a timely manner, or
at all.

We  may  be  subject  to  environmental  liability  inherent  in  our  current  and  historical  activities,  including  liability
relating  to  releases  of  or  exposure  to  hazardous  or  biological  materials.  Environmental,  health  and  safety  laws  and
regulations  are  becoming  more  stringent.  We  may  be  required  to  incur  substantial  expenses  in  connection  with  future
environmental  compliance  or  remediation  activities,  in  which  case,  our  production  efforts  or  those  of  our  third-party
manufacturers may be interrupted or delayed.

Due to our international operations, we are subject to anti-corruption laws, as well as export control laws, customs
laws, sanctions laws and other laws governing our operations. If we fail to comply with these laws, we could be subject
to civil or criminal penalties, other remedial measures and legal expenses.

Our operations are subject to anti-corruption laws, including the UK Bribery Act 2010, or Bribery Act; the U.S.
Foreign Corrupt Practices Act, or FCPA; and other anti-corruption laws that apply in countries where we do business and
may do business in the future. The Bribery Act, FCPA, and these other laws generally prohibit us, our officers and our
employees and intermediaries from bribing, being bribed by, or providing prohibited payments or anything else of value
to government officials or other persons to obtain or retain business or gain some other business advantage. We may in
the  future  operate  in  jurisdictions  that  pose  a  high  risk  of  potential  Bribery  Act  or  FCPA  violations,  and  we  may
participate  in  collaborations  and  relationships  with  third  parties  whose  actions  could  potentially  subject  us  to  liability
under the Bribery Act, FCPA, or local anti-corruption laws. In addition, we cannot predict the nature, scope, or effect of
future  regulatory  requirements  to  which  any  of  our  international  operations  might  be  subject  or  the  manner  in  which
existing laws might be administered or interpreted.

We  also  are  subject  to  other  laws  and  regulations  governing  any  international  operations,  including  regulations
administered by the governments of the UK and the U.S., and authorities in the EU, including applicable export control
regulations, economic sanctions on countries and persons, customs requirements and currency exchange regulations, or,
collectively, the Trade Control laws.

There  is  no  assurance  that  we  will  be  completely  effective  in  ensuring  our  compliance  with  all  applicable  anti-
corruption laws, including the Bribery Act, the FCPA, or other legal requirements, including Trade Control laws. If we
are not in compliance with the Bribery Act, the FCPA, and other anti-corruption laws or Trade Control laws, we may be
subject to criminal and civil penalties, disgorgement, and other sanctions and remedial measures and legal expenses. Any
investigation of any potential violations of the Bribery Act, the FCPA, other anti-corruption laws, or Trade Control laws
by UK, U.S., or other authorities, even if it is ultimately determined that we did not violate such laws, could be costly and
time-consuming, require significant personnel resources, and harm our reputation.

We  have  established  internal  controls  to  detect  and  prevent  violations  of  applicable  anti-corruption  laws  and  to
remedy any weaknesses identified. There can be no assurance, however, that the policies and procedures will be followed
at  all  times  or  effectively  detect  and  prevent  violations  of  the  applicable  laws  by  one  or  more  of  our  employees,
consultants, agents, or collaborators and, as a result, we could be subject to fines, penalties, or prosecution.

Risks Related to Commercialization

We face significant competition in an environment of rapid technological change, and there is a possibility that our
competitors may achieve regulatory approval before us or develop therapies that are safer or more advanced or
effective than ours, which may harm our financial condition and our ability to successfully market or commercialize
any product candidates we may develop.

77

Table of Contents

The development and commercialization of new gene therapy products is highly competitive. Moreover, the gene
regulation  and  manufacturing  fields  are  characterized  by  rapidly  changing  technologies  and  a  strong  emphasis  on
intellectual  property.  We  may  face  competition  with  respect  to  any  product  candidates  that  we  may  seek  to  develop  or
commercialize  in  the  future  from  major  pharmaceutical  companies,  specialty  pharmaceutical  companies,  and
biotechnology companies worldwide. Potential competitors also include academic institutions, government agencies, and
other public and private research organizations that conduct research, seek patent protection, and establish collaborative
arrangements for research, development, manufacturing, and commercialization.

There are a number of large pharmaceutical and biotechnology companies that currently market and sell products
or  are  pursuing  the  development  of  products  for  the  treatment  of  the  disease  indications  for  which  we  have  research
programs, including inherited retinal diseases and neurodegenerative diseases. Some of these competitive products and
therapies are based on scientific approaches that are similar to our approach, and others are based on entirely different
approaches. Differences in the scientific approaches may create confusion or uncertainty among clinical trial investigators
or patient populations, which could delay or hinder enrollment or initiation of our clinical trials.

Our platform and products focus on the development of gene therapies and gene regulation technology. In 2017,
the  FDA  approved  the  first  gene  treatment  for  RPE65-associated  retinal  disease,  Luxturna,  a  commercially  available
product developed by Spark Therapeutics, Inc., which was purchased by Roche. There are a number of other companies
developing  ocular  gene  therapy  products,  including  Applied  Genetic  Technologies  Corporation,  and  4D  Molecular
Therapeutics,  Inc.  There  are  a  number  of  companies  developing  gene  therapy  products  for  neurodegenerative  diseases,
including  Voyager  Therapeutics,  Inc.,  Brain  Neurotherapy  Bio,  Inc.,  Axovant  Gene  Therapies  Ltd.  and  Prevail
Therapeutics Inc. (which was purchased by Eli Lilly and Company). In addition to competition from other gene therapies,
any products we may develop may also face competition from other types of therapies, such as small molecule, antibody,
or protein therapies. Many of our current or potential competitors, either alone or with their collaboration partners, have
greater  financial  resources  and  expertise  in  research  and  development,  manufacturing,  preclinical  testing,  conducting
clinical trials, obtaining regulatory approvals, and marketing approved products than we do. Mergers and acquisitions in
the  pharmaceutical,  biotechnology,  and  gene  therapy  industries  may  result  in  even  more  resources  being  concentrated
among a smaller number of our competitors. These competitors also compete with us in recruiting and retaining qualified
scientific, manufacturing and management personnel and establishing clinical trial sites and patient enrollment in clinical
trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Our commercial opportunity
could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have
fewer  or  less  severe  side  effects,  are  more  convenient,  or  are  less  expensive  than  any  products  that  we  may  develop,
limiting demand or the price we are able to charge, or that could render any products that we may develop obsolete or
non-competitive.  Our  competitors  also  may  obtain  FDA,  MHRA  or  other  regulatory  approval  for  their  products  more
rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position
before  we  are  able  to  enter  the  market.  In  addition,  as  a  result  of  the  expiration  or  successful  challenge  of  our  patent
rights,  we  could  face  more  litigation  with  respect  to  the  validity  and/or  scope  of  patents  relating  to  our  competitors’
products.

The successful commercialization of our product candidates will depend in part on the extent to which
governmental authorities and health insurers establish coverage, adequate reimbursement levels and pricing
policies. Failure to obtain or maintain coverage and adequate reimbursement for our product candidates, if
approved, could limit our ability to market those products and decrease our ability to generate revenue.

The  availability  of  coverage  and  adequacy  of  reimbursement  by  governmental  healthcare  programs  such  as
Medicare and Medicaid, private health insurers and other third-party payors are essential for most patients to be able to
afford medical services and pharmaceutical products such as our product candidates, assuming FDA approval. Our ability
to  achieve  acceptable  levels  of  coverage  and  reimbursement  for  our  products  or  procedures  using  our  products  by
governmental authorities, private health insurers and other organizations will have an effect on our ability to successfully
commercialize  our  product  candidates.  Obtaining  coverage  and  adequate  reimbursement  for  our  products  may  be
particularly difficult because of the higher prices often associated with drugs administered under the supervision of a

78

Table of Contents

physician. Separate reimbursement for the product itself or the treatment or procedure in which our product is used may
not be available. A decision by a third-party payor not to cover or separately reimburse for our products or procedures
using our products, could reduce physician utilization of our products if approved. Assuming there is such coverage by a
third-party  payor,  the  resulting  reimbursement  payment  rates  may  not  be  adequate  or  may  require  co-payments  that
patients find unacceptably high. We cannot be sure that coverage and reimbursement in the United States, the UK, the EU
or elsewhere will be available for our product candidates or any product that we may develop, and any reimbursement
that may become available may not be adequate or may be decreased or eliminated in the future.

Third-party  payors  increasingly  are  challenging  prices  charged  for  pharmaceutical  products  and  services,  and
many  third-party  payors  may  refuse  to  provide  coverage  and  reimbursement  for  particular  drugs  or  biologics  when  an
equivalent  generic  drug,  biosimilar  or  a  less  expensive  therapy  is  available.  It  is  possible  that  a  third-party  payor  may
consider our product candidates as substitutable and only offer to reimburse patients for the less expensive product. Even
if we show improved efficacy or improved convenience of administration with our product candidates, pricing of existing
third-party  therapeutics  may  limit  the  amount  we  will  be  able  to  charge  for  our  product  candidates.  These  payors  may
deny or revoke the reimbursement status of a given product or establish prices for new or existing marketed products at
levels  that  are  too  low  to  enable  us  to  realize  an  appropriate  return  on  our  investment  in  our  product  candidates.  If
reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize
our product candidates and may not be able to obtain a satisfactory financial return on our product candidates.

There is significant uncertainty related to the insurance coverage and reimbursement of newly-approved products.
In the United States, third-party payors, including private and governmental payors, such as the Medicare and Medicaid
programs,  play  an  important  role  in  determining  the  extent  to  which  new  drugs  and  biologics  will  be  covered.  The
Medicare and Medicaid programs increasingly are used as models in the United States for how private payors and other
governmental payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors
may  require  pre-approval  of  coverage  for  new  or  innovative  devices  or  drug  therapies  before  they  will  reimburse
healthcare  providers  who  use  such  therapies.  We  cannot  predict  at  this  time  what  third-party  payors  will  decide  with
respect to the coverage and reimbursement for our product candidates.

No  uniform  policy  for  coverage  and  reimbursement  for  products  exists  among  third-party  payors  in  the  United
States. Therefore, coverage and reimbursement for products can differ significantly from payor to payor. As a result, the
coverage determination process is often a time-consuming and costly process that will require us to provide scientific and
clinical  support  for  the  use  of  our  product  candidates  to  each  payor  separately,  with  no  assurance  that  coverage  and
adequate reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations
regarding reimbursement change frequently, in some cases on short notice.

Outside the United States, international operations are generally subject to extensive governmental price controls
and other market regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe and other
countries have and will continue to put pressure on the pricing and usage of our product candidates. In many countries,
the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other
countries  allow  companies  to  fix  their  own  prices  for  medical  products  but  monitor  and  control  company  profits.
Additional  foreign  price  controls  or  other  changes  in  pricing  regulation  could  restrict  the  amount  that  we  are  able  to
charge for our product candidates. Accordingly, in markets outside the United States, the reimbursement for our product
candidates may be reduced compared with the United States and may be insufficient to generate commercially-reasonable
revenue and profits.

Moreover,  increasing  efforts  by  governmental  and  third-party  payors  in  the  United  States  and  abroad  to  cap  or
reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly
approved  products  and,  as  a  result,  they  may  not  cover  or  provide  adequate  payment  for  our  product  candidates.  We
expect  to  experience  pricing  pressures  in  connection  with  the  sale  of  our  product  candidates  due  to  the  trend  toward
managed health care, the increasing influence of health maintenance organizations and additional legislative changes. The
downward pressure on healthcare costs in general, particularly prescription drugs and biologics and surgical

79

Table of Contents

procedures and other treatments, has become intense. As a result, increasingly high barriers are being erected to the entry
of new products.

Even if our product candidates receive marketing approval, they may fail to achieve market acceptance by
physicians, patients, third-party payors or others in the medical community necessary for commercial success.

If  our  product  candidates  receive  marketing  approval,  they  may  nonetheless  fail  to  gain  sufficient  market
acceptance  by  physicians,  patients,  third-party  payors  and  others  in  the  medical  community.  If  they  do  not  achieve  an
adequate  level  of  acceptance,  we  may  not  generate  significant  product  revenues  or  become  profitable.  The  degree  of
market  acceptance  of  our  product  candidates,  if  approved  for  commercial  sale,  will  depend  on  a  number  of  factors,
including but not limited to:

● the efficacy and potential advantages compared to alternative treatments;

● effectiveness of sales and marketing efforts;

● the cost of treatment in relation to alternative treatments, including any similar generic treatments;

● our ability to offer our product candidates for sale at competitive prices;

● the convenience and ease of administration;

● the willingness of the target patient population to try new therapies and of physicians to prescribe these

therapies;

● the strength of marketing and distribution support, and publicity concerning our products or competing

products and treatments;

● the timing of market introduction of competitive products;

● the availability of third-party coverage and adequate reimbursement;

● product labeling or product insert requirements of the FDA, MHRA, EMA or other regulatory
authorities, including any limitations or warnings contained in a product’s approved labeling;

● the prevalence and severity of any side effects; and

● any restrictions on the use of our product together with other medications.

Because  we  expect  sales  of  our  product  candidates,  if  approved,  to  generate  substantially  all  of  our  product
revenues  for  a  substantial  period,  the  failure  of  these  product  candidates  to  find  market  acceptance  would  harm  our
business and could require us to seek additional financing.

If we are unable to establish sales, marketing and distribution capabilities either on our own or in collaboration
with third parties, we may not be successful in commercializing our product candidates or realizing the synergies in
the target indications of our programs, even if they are approved.

We  do  not  have  any  infrastructure  for  the  sales,  marketing  or  distribution  of  our  products,  and  the  cost  of
establishing  and  maintaining  such  an  organization  may  exceed  the  cost-effectiveness  of  doing  so  or  we  may  seek
collaborative  arrangements  or  external  funding  to  commercialize  our  product  candidates.  For  example,  Janssen  will  be
solely responsible for the commercialization of botaretigene sparoparvovec, AAV-CNGB3 and AAV-CNGA3 pursuant

80

Table of Contents

to our Collaboration Agreement with them. There are significant expenses and risks involved with establishing our own
sales, marketing and distribution capabilities, including our ability to hire, retain and appropriately incentivize qualified
individuals,  generate  sufficient  sales  leads,  provide  adequate  training  to  sales  and  marketing  personnel,  and  effectively
manage a geographically dispersed sales and marketing team. Any failure or delay in the development of such capabilities
could  delay  any  product  launch,  which  would  adversely  impact  the  commercialization  of  our  product  candidates.
Additionally,  if  any  commercial  launch  is  delayed  or  does  not  occur  for  any  reason,  we  would  have  prematurely  or
unnecessarily  incurred  these  commercialization  expenses.  This  may  be  costly,  and  our  investment  would  be  lost  if  we
cannot retain or reposition our sales and marketing personnel.

We  may  not  have  the  resources  in  the  foreseeable  future  to  allocate  to  the  sales  and  marketing  of  our  product
candidates in certain markets. Therefore, our future sales in these markets will largely depend on our ability to enter into
and maintain collaborative relationships for such capabilities, the collaborator’s strategic interest in the product and such
collaborator’s ability to successfully market and sell the product. We may pursue collaborative arrangements regarding
the sale and marketing of AAV-GAD, AAV-RPE65, AAV-hAQP1 or other future gene therapy programs, if approved, for
the United States and/or certain markets overseas; however, there can be no assurance that we will be able to establish or
maintain such collaborative arrangements, or if able to do so, that they will have effective sales forces.

If  we  are  unable  to  build  our  own  sales  force  or  negotiate  or  maintain  a  collaborative  relationship  for  the
commercialization of our product candidates, we may be forced to delay potential commercialization or reduce the scope
of  our  sales  or  marketing  activities.  If  we  elect  to  increase  our  expenditures  to  fund  commercialization  activities
internationally, we will need to obtain additional capital, which may not be available to us on acceptable terms, or at all.
We could enter into arrangements with collaborative partners at an earlier stage than otherwise would be ideal and we
may be required to relinquish rights or otherwise agree to terms unfavorable to us, any of which may have an adverse
effect on our business, operating results and prospects.

Some  indications  targeted  by  our  ophthalmology  programs  are  rare,  but  we  anticipate  realizing  synergies  in
commercializing  our  IRD  product  candidates,  should  they  be  approved.  Failure  to  realize  synergies  in  our  sales,
marketing and distribution efforts may harm our commercialization efforts.

If  we  or  our  collaborators  are  unable  to  establish  or  maintain  adequate  sales,  marketing  and  distribution
capabilities, we will not be successful in commercializing our product candidates and may not become profitable and may
incur significant additional losses. We will be competing with many companies that currently have extensive and well-
funded marketing and sales operations. Without an internal team or the support of a third party to perform marketing and
sales functions, we may be unable to compete successfully against these more established companies.

If any of our products are commercialized outside of the United States, the UK or the EU, a variety of risks
associated with international operations could adversely affect our business.

If  any  of  our  products  are  approved  for  commercialization,  we  have  entered  into,  and  intend  to  enter  into,
agreements with third parties to market them in certain jurisdictions outside the United States, the UK and the EU, such
as under our Collaboration Agreement with Janssen. We expect that we and our third-party collaborators will be subject
to additional risks related to international pharmaceutical operations, including:

● different regulatory requirements for drug and biologic approvals and rules governing drug and biologic

commercialization in foreign countries;

● tighter restrictions on privacy and the collection and use of patient data;

● reduced or loss of protection for intellectual property rights;

● foreign reimbursement, pricing and insurance regimes;

81

Table of Contents

● unexpected changes in tariffs, trade barriers and regulatory requirements;

● economic weakness, including inflation, or political instability in particular foreign economies and

markets;

● foreign currency fluctuations, which could result in increased operating expenses and reduced revenues,

and other obligations incident to doing business in another country;

● business  interruptions  resulting  from  geopolitical  actions,  including  war  and  terrorism,  or  widespread
health  emergencies,  such  as  the  COVID-19  pandemic,  or  natural  disasters  including  earthquakes,
typhoons, floods and fires, or from economic or political instability;

● greater difficulty with enforcing our contracts;

● potential noncompliance with the FCPA, the Bribery Act and similar anti-bribery and anticorruption

laws in other jurisdictions;

● production shortages resulting from any events affecting raw material supply or manufacturing

capabilities abroad; and

● workforce  uncertainty  in  countries  where  labor  unrest  is  more  common  than  in  the  United  States  and
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad.

We  have  no  prior  experience  in  these  areas  and  we  may  rely  on  other  third  parties  to  help  us  establish  our
international  commercialization  operations.  In  addition,  there  are  complex  regulatory,  tax,  labor  and  other  legal
requirements  imposed  by  individual  countries  in  Europe  with  which  we  and  our  third-party  collaborators  will  need  to
comply. If we are unable to successfully manage the challenges of international expansion and operations, our business
and operating results could be harmed.

Any product candidates for which we intend to seek approval as biologic products may face competition sooner
than anticipated.

The ACA includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which
created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-
licensed reference biological product. Under the BPCIA, an application for a biosimilar product may not be submitted to
the  FDA  until  four  years  following  the  date  that  the  reference  product  was  first  licensed  by  the  FDA.  In  addition,  the
approval  of  a  biosimilar  product  may  not  be  made  effective  by  the  FDA  until  12  years  from  the  date  on  which  the
reference  product  was  first  licensed  by  the  FDA.  During  this  12-year  period  of  exclusivity,  another  company  may  still
market  a  competing  version  of  the  reference  product  if  the  FDA  approves  a  full  BLA  for  the  competing  product
containing the sponsor’s own pre-clinical data and data from adequate and well-controlled clinical trials to demonstrate
the safety, purity and potency of the other company’s product.

We believe that any of our product candidates approved as a biological product under a BLA should qualify for
the  12-year  period  of  exclusivity.  However,  there  is  a  risk  that  any  of  our  product  candidates  approved  as  a  biological
product under a BLA would not qualify for the 12-year period of exclusivity or that this exclusivity could be shortened
due  to  Congressional  action  or  otherwise,  or  that  the  FDA  will  not  consider  our  product  candidates  to  be  reference
products  for  competing  products,  potentially  creating  the  opportunity  for  generic  competition  sooner  than  anticipated.
Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of
recent litigation. Jurisdictions outside the United States have established abbreviated pathways for regulatory approval

82

Table of Contents

of  biological  products  that  are  biosimilar  to  earlier  approved  reference  products.  For  example,  the  EU  has  had  an
established regulatory pathway for biosimilars since 2006. Moreover, the extent to which a biosimilar, once licensed, will
be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-
biological  products  is  not  yet  clear,  and  will  depend  on  a  number  of  marketplace  and  regulatory  factors  that  are  still
developing.

If competitors are able to obtain marketing approval for biosimilars referencing our products, our products may

become subject to competition from such biosimilars, with the attendant competitive pressure and consequences.

Risks Related to Our Dependence on Third Parties

If our cGMP and GMP manufacturing facilities are unable to supply our product candidates for all of our current
preclinical, clinical and potential commercial needs, we will be forced to seek out third-party manufacturers. We
currently contract with third parties for the manufacture of plasmid used in producing our product candidates.
Relying on third parties increases the risk that we will not have sufficient quantities of such materials, product
candidates, or any medicines that we may develop and commercialize, or that such supply will not be available to us at
an acceptable cost, which could delay, prevent, or impair our development or commercialization efforts.

We produce our product candidates in our cGMP viral vector manufacturing facility completed in early 2018 and
we  completed  the  acquisition  of  our  second,  large  scale  cGMP  viral  vector  manufacturing  facility  and  our  first  cGMP
plasmid and DNA production facility in Shannon, Ireland in January 2021 to expand our manufacturing and supply chain
capabilities.  However,  if  our  current  facility  is  damaged,  suffers  any  form  of  delay  or  regulatory  challenges,  we
experience slowdowns or problems with the development and completion of our new facilities or we are unable to scale
our internal manufacturing capabilities to meet demand for our product candidates, we will need to contract with third-
party manufacturers to produce our product candidates. While we now have our own plasmid manufacturing capabilities
in our Shannon, Ireland facilities, we may also rely on third-party manufacturers from time to time for the manufacture of
plasmid used in the production of some of our product candidates. We do not have a long-term supply agreement with any
of the third-party manufacturers, and we purchase our required supply on a purchase order basis.

We and our third-party manufacturers may also encounter difficulties or delays in manufacturing of our product
candidates  or  the  plasmid  used  in  the  production  of  our  product  candidates.  Geopolitical  actions,  natural  disaster  or  a
widespread health emergency, such as the COVID-19 pandemic, could impact our supply chain. To the extent that we or
our third-party manufacturers are located in geographies affected by these matters, it may result in the temporary closing
of manufacturing facilities and may increase the costs associated with manufacturing our product candidates.

We  may  be  unable  to  establish  any  agreements  with  third-party  manufacturers  or  to  do  so  on  acceptable  terms.
Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails
additional risks, including:

● the possible breach of the manufacturing agreement by the third party, including failure to provide

appropriate quantities in a timely manner;

● the possible termination or nonrenewal of the agreement by the third party at a time that is costly or

inconvenient for us; and

● reliance on the third party for regulatory compliance, quality assurance, safety, and pharmacovigilance

and related reporting.

We  and  our  third-party  manufacturers  may  not  be  able  to  comply  with  cGMP  regulations  or  similar  regulatory
requirements  that  might  be  required  by  the  FDA,  MHRA  or  EMA.  Our  failure,  or  the  failure  of  our  third-party
manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including fines,

83

Table of Contents

injunctions,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals,  license  revocations,  seizures  or  recalls  of
product candidates or medicines, operating restrictions, and criminal prosecutions, any of which could adversely affect
supplies of our candidates and harm our business, financial condition, results of operations, and prospects.

Any  therapies  that  we  may  develop  may  compete  with  other  product  candidates  and  products  for  access  to
manufacturing facilities. There are a limited number of manufacturers that operate under cGMP or similar regulations and
that  might  be  capable  of  manufacturing  for  us.  Any  performance  failure  on  the  part  of  our  existing  or  future
manufacturers could delay clinical development or marketing approval.

Our current and anticipated future dependence upon others for the manufacture of any product candidates we may
develop or any components required for the manufacture of our product candidates may adversely affect our future profit
margins  and  our  ability  to  commercialize  any  product  candidates  that  receive  marketing  approval  on  a  timely  and
competitive basis.

We have in the past, and may in the future, collaborate with third parties for the development, manufacture and
commercialization of our product candidates. We may not succeed in establishing and maintaining
collaborative relationships, which may significantly limit our ability to develop and commercialize our product
candidates successfully, if at all.

We have entered into collaboration agreements with third parties for the development and commercialization of
our product candidates, including our Collaboration Agreement with Janssen for the development and commercialization
of  AAV-CNGB3,  AAV-CNGA3  and  botaretigene  sparoparvovec.  We  have  also  entered  into  a  manufacturing  research
collaboration  agreement  with  Janssen  to  further  develop  processes  for  manufacturing  AAV  viral  vectors.  We  may  seek
additional  collaborative  relationships  in  the  future.  Failure  to  obtain  a  collaborative  relationship  for  our  product
candidates may significantly impair their commercial potential. We also may need to enter into collaborative relationships
to provide funding to support our other research and development programs. The process of establishing and maintaining
collaborative relationships is difficult, time-consuming and involves significant uncertainty, such as:

● a collaboration partner may shift its priorities and resources away from our product candidates due to a

change in business strategies, or a merger, acquisition, sale or downsizing;

● a  collaboration  partner  may  seek  to  renegotiate  or  terminate  their  relationships  with  us  due  to
unsatisfactory clinical results, manufacturing issues, a change in business strategy, a change of control
or other reasons;

● a collaboration partner may cease development in therapeutic areas which are the subject of our strategic

collaboration;

● a collaboration partner may not devote sufficient capital or resources towards our product candidates;

● a collaboration partner may change the success criteria for a product candidate thereby delaying or

ceasing development of such candidate;

● a  significant  delay  in  initiation  of  certain  development  activities  by  a  collaboration  partner  will  also
delay  payment  of  milestones  tied  to  such  activities,  thereby  impacting  our  ability  to  fund  our  own
activities;

● a collaboration partner could develop a product that competes, either directly or indirectly, with our

product candidate;

84

Table of Contents

● a collaboration partner with commercialization obligations may not commit sufficient financial or

human resources to the marketing, distribution or sale of a product;

● a collaboration partner with manufacturing responsibilities may encounter regulatory, resource or quality

issues and be unable to meet demand requirements;

● a collaboration partner may terminate a strategic alliance;

● a  dispute  may  arise  between  us  and  a  partner  concerning 

the  research,  development  or
commercialization  of  a  product  candidate  resulting  in  a  delay  in  milestones,  royalty  payments  or
termination  of  an  alliance  and  possibly  resulting  in  costly  litigation  or  arbitration  which  may  divert
management attention and resources; and

● a partner may use our products or technology in such a way as to make us subject to litigation with a

third party.

If  any  collaborator  fails  to  fulfill  its  responsibilities  in  a  timely  manner,  or  at  all,  our  research,  clinical
development, manufacturing or commercialization efforts related to that collaboration could be delayed or terminated, or
it  may  be  necessary  for  us  to  assume  responsibility  for  expenses  or  activities  that  would  otherwise  have  been  the
responsibility  of  our  collaborator.  If  we  are  unable  to  establish  and  maintain  collaborative  relationships  on  acceptable
terms  or  to  successfully  transition  terminated  collaborative  agreements,  we  may  have  to  delay  or  discontinue  further
development of one or more of our product candidates, undertake development and commercialization activities at our
own expense or find alternative sources of capital.

We have relied, and we expect to continue to rely, on third parties to conduct, supervise and monitor our preclinical
studies  and  clinical  trials,  and  if  these  third  parties  perform  in  an  unsatisfactory  manner,  our  business  could  be
harmed.

We  expect  to  rely  on  CROs,  clinical  trial  sites,  and  other  vendors  to  ensure  our  preclinical  studies  and  clinical
trials  are  conducted  properly  and  on  time.  We  may  also  engage  third  parties  such  as  clinical  data  management
organizations, medical institutions and clinical investigators to conduct or assist in our clinical trials or other preclinical
and  clinical  research  and  development  work.  While  we  will  have  agreements  governing  their  activities,  we  will  have
limited influence over their actual performance. We will control only certain aspects of our third-party service providers’
activities.  Nevertheless,  we  will  be  responsible  for  ensuring  that  each  of  our  preclinical  studies  and  clinical  trials  is
conducted in accordance with the applicable protocol, legal, quality, regulatory and scientific standards. Our reliance on
these  third  parties  does  not  relieve  us  of  our  regulatory  responsibilities.  For  example,  we  are  conducting  the  Phase  3
Lumeos clinical trial of botaretigene sparoparvovec for the treatment of patients with XLRP caused by mutations in the
RPGR gene at multiple clinical trial sites in North America and Europe. If any locations terminate the clinical trial, we
may be required to find another party to conduct any new trials. We may be unable to find a new party to conduct new
trials of our product candidates or obtain clinical supply of our product candidates or AAV vectors for such trials. If we
elect to internalize some or all activities related to the conduct of our preclinical studies or clinical trials that are currently
performed by our third-party service providers, or if we are required to do so due to a service provider’s termination of
our relationship, then we may be required to source additional technology and personnel in order to perform the relevant
activities.  We  may  be  unsuccessful  in  our  efforts  to  internalize  some  or  all  relevant  activities,  either  on  the  desired
timeline or at all.

Our third-party service providers are not our employees, and we are therefore unable to directly monitor whether
or not they devote sufficient time, attention, expertise and resources to our clinical and nonclinical programs. These third-
party service providers may also have relationships with other commercial entities, including our competitors, for whom
they may also be conducting clinical trials or other drug development activities that could harm our competitive position.
If our third-party service providers do not successfully carry out their contractual duties or obligations or fail to meet

85

Table of Contents

expected deadlines, or if the quality or accuracy of the preclinical or clinical data they obtain is compromised due to the
failure to adhere to our clinical protocols or regulatory requirements, or for any other reasons, our preclinical studies or
clinical  trials  may  be  extended,  delayed  or  terminated,  and  we  may  not  be  able  to  obtain  regulatory  approval  for,  or
successfully commercialize our product candidates. As a result, our financial results and the commercial prospects for our
product candidates could be harmed, our costs could increase, and our ability to generate revenues could be delayed.

If our relationship with any CROs terminate, we may not be able to enter into arrangements with alternative CROs
or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires
management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a
result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though
we  intend  to  carefully  manage  our  relationships  with  our  CROs,  there  can  be  no  assurance  that  we  will  not  encounter
challenges  or  delays  in  the  future  or  that  these  delays  or  challenges  will  not  have  an  adverse  impact  on  our  business,
financial condition and prospects.

Risks Related to Intellectual Property

We depend on proprietary technology licensed from others. If we lose our existing licenses or are unable to acquire
or license additional proprietary rights from third parties, we may not be able to continue developing our product
candidates.

We currently in-license certain intellectual property from research institutions, universities and other third parties.
We may also enter into additional agreements, including license agreements, with other parties in the future that impose
diligence, development and commercialization timelines, milestone payments, royalties, insurance and other obligations
on us. If we fail to comply with our obligations to any of our current or future collaborators, our counterparties may have
the  right  to  terminate  these  agreements,  in  which  event  we  might  not  be  able  to  develop,  manufacture  or  market  any
product candidate that is covered by these agreements, which could adversely affect the value of the product candidate
being  developed  under  any  such  agreement.  Termination  of  these  agreements  or  reduction  or  elimination  of  our  rights
under these agreements may result in our having to negotiate new or reinstated agreements with less favorable terms, or
cause us to lose our rights under these agreements, including our rights to important intellectual property or technology.

We  may  rely  on  other  third  parties  from  whom  we  license  proprietary  technology  to  file  and  prosecute  patent
applications  and  maintain  patents  and  otherwise  protect  the  intellectual  property  we  license  from  them.  We  may  have
limited control over these activities or any other intellectual property that may be related to our in-licensed intellectual
property. For example, we cannot be certain that such activities by these licensors will be conducted in compliance with
applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. We
may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party
infringer of the intellectual property rights, or defend certain of the intellectual property that may be licensed to us. It is
possible that the licensors’ infringement proceedings or defense activities may be less vigorous than if we conduct them
ourselves.  The  licensing  and  acquisition  of  third-party  intellectual  property  rights  is  a  competitive  practice,  and
companies that may be more established, or have greater resources than we do, may also be pursuing strategies to license
or acquire third-party intellectual property rights that we may consider necessary or attractive in order to commercialize
our product candidates. More established companies may have a competitive advantage over us due to their larger size
and cash resources or greater clinical development and commercialization capabilities. There can be no assurance that we
will  be  able  to  successfully  complete  such  negotiations  and  ultimately  acquire  the  rights  to  the  intellectual  property
surrounding the additional product candidates that we may seek to acquire. If we are unable to obtain and maintain patent
protection for our technology and product candidates or if the scope of the patent protection obtained is not sufficiently
broad, we may not be able to compete effectively in our markets.

86

Table of Contents

If we are unable to obtain and maintain patent protection for our technology and product candidates or if the scope
of the patent protection obtained is not sufficiently broad, we may not be able to compete effectively in our markets.

We  rely  upon  a  combination  of  patents,  trade  secret  protection  and  confidentiality  agreements  to  protect  the
intellectual  property  related  to  our  proprietary  technologies,  product  candidate  development  programs  and  product
candidates. Our success depends in part on our ability to secure and maintain patent protection in the United States and
other  countries  with  respect  to  our  current  product  candidates  and  any  future  product  candidates  we  may  develop.  We
seek  to  protect  our  proprietary  position  by  filing  or  collaborating  with  our  licensors  to  file  patent  applications  in  the
United  States  and  abroad  related  to  our  proprietary  technologies,  development  programs  and  product  candidates.  The
patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary
or  desirable  patent  applications  at  a  reasonable  cost  or  in  a  timely  manner.  Moreover,  the  issuance,  scope,  validity,
enforceability and commercial value of our patent rights are uncertain.

It is also possible that we might fail to identify patentable aspects of our research and development output before it
is  too  late  to  obtain  patent  protection.  We  may  not  have  the  right  to  control  the  preparation,  filing,  and  prosecution  of
patent  applications,  or  to  maintain  the  rights  to  patents  licensed  to  third  parties.  Therefore,  these  patents  and  patent
applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. The patent
applications that we own or in-license may fail to result in issued patents with claims that cover our proprietary products
and  technology,  including  current  product  candidates,  any  future  product  candidates  we  may  develop,  and  our  gene
regulation technology in the United States or in other countries, in whole or in part. Alternately, our existing patents and
any  future  patents  we  obtain  may  not  be  sufficiently  broad  to  prevent  others  from  using  our  technology  or  from
developing competing products and technologies. There is no assurance that all potentially relevant prior art relating to
our  patents  and  patent  applications  has  been  found,  which  can  prevent  a  patent  from  issuing  from  a  pending  patent
application  or  later  invalidate  or  narrow  the  scope  of  an  issued  patent.  For  example,  publications  of  discoveries  in  the
scientific  literature  often  lag  behind  the  actual  discoveries,  and  patent  applications  in  the  United  States  and  other
jurisdictions  are  typically  not  published  until  18  months  after  filing  or,  in  some  cases,  not  at  all.  Therefore,  we  cannot
know  with  certainty  whether  we  were  the  first  to  make  the  inventions  claimed  in  our  patents  or  pending  patent
applications,  or  that  we  were  the  first  to  file  for  patent  protection  of  such  inventions.  In  addition,  obtaining  and
maintaining  our  patent  protection  depends  on  compliance  with  various  procedural,  document  submission,  fee  payment
and  other  requirements  imposed  by  governmental  patent  agencies,  and  our  patent  protection  could  be  reduced  or
eliminated  for  non-compliance  with  these  requirements.  Even  if  patents  do  successfully  issue  and  even  if  such  patents
cover our current product candidates, any future product candidates we may develop and our gene regulation technology,
third  parties  may  challenge  their  validity,  enforceability  or  scope  thereof,  which  may  result  in  such  patents  being
narrowed, invalidated, or held unenforceable. Any successful challenge to these patents or any other patents owned by or
licensed to us could deprive us of rights necessary for the successful commercialization of any of our product candidates
or  gene  regulation  technology.  Our  competitors  may  be  able  to  circumvent  our  patents  by  developing  similar  or
alternative  product  candidates  in  a  non-infringing  manner.  Further,  if  we  encounter  delays  in  regulatory  approvals,  the
period  of  time  during  which  we  could  market  a  product  candidate  and  our  gene  regulation  technology  under  patent
protection could be reduced.

If  the  patent  applications  we  hold  or  have  in-licensed  with  respect  to  our  development  programs  and  product
candidates  fail  to  issue,  if  their  validity,  breadth  or  strength  of  protection  is  threatened,  or  if  they  fail  to  provide
meaningful  exclusivity  for  any  of  our  current  or  future  product  candidates  or  technology,  it  could  dissuade  companies
from  collaborating  with  us  to  develop  product  candidates,  encourage  competitors  to  develop  competing  products  or
technologies  and  threaten  our  ability  to  commercialize  future  product  candidates.  Any  such  outcome  could  harm  our
business.

The  patent  position  of  biotechnology  and  pharmaceutical  companies  is  uncertain,  involves  complex  legal  and
factual  questions,  and  is  characterized  by  the  existence  of  large  numbers  of  patents  and  frequent  litigation  based  on
allegations of patent or other intellectual property infringement or violation. In addition, the laws of jurisdictions outside

87

Table of Contents

the United States may not protect our rights to the same extent as the laws of the United States. Changes in either the
patent  laws  or  interpretation  of  the  patent  laws  in  the  United  States  and  other  countries  may  diminish  the  value  of  our
patents or narrow the scope of our patent protection.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned
and licensed patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges
may  result  in  loss  of  exclusivity  or  freedom  to  operate  or  in  patent  claims  being  narrowed,  invalidated  or  held
unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or
identical  technology  and  products,  or  limit  the  duration  of  the  patent  protection  of  our  technology  and  products.  Thus,
even  if  our  patent  applications  issue  as  patents,  they  may  not  issue  in  a  form  that  will  provide  us  with  meaningful
protection,  prevent  competitors  from  competing  with  us  or  otherwise  provide  us  with  any  competitive  advantage.
Moreover, patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years
after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited.
Without  patent  protection  for  our  current  or  future  product  candidates,  we  may  be  open  to  competition  from  generic
versions of such products. Given the amount of time required for the development, testing and regulatory review of new
product  candidates,  patents  protecting  such  candidates  might  expire  before  or  shortly  after  such  candidates  are
commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude
others from commercializing products similar or identical to ours.

Third parties may assert claims against us alleging infringement of their patents and proprietary rights, or we may
need to become involved in lawsuits to defend or enforce our patents, either of which could result in substantial costs
or loss of productivity, delay or prevent the development and commercialization of our product candidates, prohibit
our use of proprietary technology or sale of products or put our patents and other proprietary rights at risk.

Our commercial success depends, in part, upon our ability to develop, manufacture, market and sell our product
candidates without alleged or actual infringement, misappropriation or other violation of the patents and proprietary rights
of third parties. However, our research, development and commercialization activities may be subject to claims that we
infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Litigation
relating  to  infringement  or  misappropriation  of  patent  and  other  intellectual  property  rights  in  the  pharmaceutical  and
biotechnology industries is common, including patent infringement lawsuits, interferences, oppositions and inter partes
reviews,  and  reexamination  proceedings  before  the  U.S.  Patent  and  Trademark  Office,  or  USPTO,  and  corresponding
foreign  patent  offices.  In  addition,  many  companies  in  intellectual  property-dependent  industries,  including  the
biotechnology  and  pharmaceutical  industries,  have  employed  intellectual  property  litigation  as  a  means  to  gain  an
advantage over their competitors. Numerous U.S., EU and foreign issued patents and pending patent applications, which
are owned by third parties, exist in the fields in which we are developing product candidates, and as the biotechnology
and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may be
subject  to  claims  of  infringement  of  the  intellectual  property  rights  of  third  parties.  Some  claimants  may  have
substantially greater resources than we do and may be able to sustain the costs of complex intellectual property litigation
to a greater degree and for longer periods of time than we could. In addition, patent holding companies that focus solely
on extracting royalties and settlements by enforcing patent rights may target us.

We may be subject to third-party claims including infringement, interference or derivation proceedings, post-grant
review and inter partes review before the USPTO or similar adversarial proceedings or litigation in other jurisdictions.
Even if such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid,
enforceable  and  infringed,  and  the  holders  of  any  such  patents  may  be  able  to  block  our  ability  to  commercialize  the
applicable product candidate unless we obtained a license under the applicable patents, or until such patents expire or are
finally determined to be invalid or unenforceable. In addition, third parties may obtain patents in the future and claim that
use of our technologies infringes upon these patents, and the holders of any such patents may be able to prohibit our use
of those compositions, formulations, methods of treatment, prevention or use or other technologies, effectively blocking
our  ability  to  develop  and  commercialize  the  applicable  product  candidate  until  such  patent  expires  or  is  finally
determined to be invalid or unenforceable or unless we obtained a license.

In addition, defending such claims would cause us to incur substantial expenses and, if we are not successful in
defending such claims, it could cause us to pay substantial damages if we are found to be infringing a third party’s patent
rights.  These  damages  potentially  include  increased  damages  (possibly  treble  damages)  and  attorneys’  fees  if  we  are
found to have infringed such rights willfully. Further, if a patent infringement suit is brought against us or our third-party
service providers, our development, manufacturing or sales activities relating to the product or product candidate that is
the  subject  of  the  suit  may  be  delayed  or  terminated.  As  a  result  of  patent  infringement  claims,  or  in  order  to  avoid
potential infringement claims, we may choose to seek, or be required to seek, a license from the third party, which may
require  payment  of  substantial  royalties  or  fees,  or  require  us  to  grant  a  cross-license  under  our  intellectual  property
rights. These licenses may not be available on reasonable terms or at all. Even if a license can be obtained on reasonable
terms, the rights may be nonexclusive, which would give our competitors access to the same intellectual property rights.
If we are unable to enter into a license on acceptable terms, we could be prevented from commercializing one or more of
our product candidates, or forced to modify such product candidates, or to cease some aspect of our business operations,
which could harm our business significantly. We might also be forced to redesign or modify our product candidates so
that we no longer infringe the third-party intellectual property rights, which may result in significant cost or delay to us,
or which redesign or modification could be impossible or technically infeasible. Even if we were ultimately to prevail,
any of these events could require us to divert substantial financial and management resources that we would otherwise be
able to devote to our business.

Competitors may infringe our patents or other intellectual property. If we or one of our licensors were to initiate
legal proceedings against a third party to enforce a patent covering one of our product candidates, the defendant could
counterclaim that our patent is invalid or unenforceable. If a defendant were to prevail on a legal assertion of invalidity or
unenforceability, we would lose at least part, and perhaps all, of the patent protection on our product candidates.

Even  if  resolved  in  our  favor,  litigation  or  other  legal  proceedings  relating  to  intellectual  property  claims  may
cause  us  to  incur  significant  expenses  and  could  distract  our  technical  and  management  personnel  from  their  normal
responsibilities.  In  addition,  because  of  the  substantial  amount  of  discovery  required  in  connection  with  intellectual
property litigation, there is a risk that some of our confidential information could be compromised by disclosure during
this  type  of  litigation.  Such  litigation  or  proceedings  could  substantially  increase  our  operating  losses  and  reduce  our
resources  available  for  development  activities.  We  may  not  have  sufficient  financial  or  other  resources  to  adequately
conduct  such  litigation  or  proceedings.  Some  of  our  competitors  may  be  able  to  sustain  the  costs  of  such  litigation  or
proceedings  more  effectively  than  we  can  because  of  their  substantially  greater  financial  resources.  Uncertainties
resulting from the initiation and continuation of patent litigation or other proceedings could have an adverse effect on our
ability to compete in the marketplace.

We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a
third-party patent, which might adversely affect our ability to develop, manufacture and market our product
candidates.

We cannot guarantee that any of our or our licensors’ patent searches or analyses, including but not limited to the
identification  of  relevant  patents,  analysis  of  the  scope  of  relevant  patent  claims  or  determination  of  the  expiration  of
relevant patents, are complete or thorough, nor can we be certain that we have identified each and every third-party patent
and  pending  application  in  the  United  States,  the  UK,  the  EU  and  elsewhere  that  is  relevant  to  or  necessary  for  the
commercialization  of  our  product  candidates  in  any  jurisdiction.  For  example,  in  the  United  States,  applications  filed
before  November  29,  2000  and  certain  applications  filed  after  that  date  that  will  not  be  filed  outside  the  United  States
remain  confidential  until  patents  issue.  Patent  applications  in  the  United  States,  the  UK,  the  EU  and  elsewhere  are
published  approximately  18  months  after  the  earliest  filing  for  which  priority  is  claimed,  with  such  earliest  filing  date
being commonly referred to as the priority date. Therefore, patent applications covering our product candidates could be
filed by others without our knowledge. Additionally, pending patent applications that have been published can, subject to
certain  limitations,  be  later  amended  in  a  manner  that  could  cover  our  product  candidates  or  the  use  of  our  product
candidates. After issuance, the scope of patent claims remains subject to construction as determined by an interpretation

89

Table of Contents

of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the
scope  of  a  patent  or  a  pending  application  may  be  incorrect,  which  may  negatively  impact  our  ability  to  market  our
product candidates. We may incorrectly determine that our product candidates are not covered by a third-party patent or
may  incorrectly  predict  whether  a  third  party’s  pending  application  will  issue  with  claims  of  relevant  scope.  Our
determination  of  the  expiration  date  of  any  patent  in  the  United  States,  the  UK,  the  EU  or  elsewhere  that  we  consider
relevant may be incorrect, which may negatively impact our ability to develop and market our product candidates. Our
failure  to  identify  and  correctly  interpret  relevant  patents  may  negatively  impact  our  ability  to  develop  and  market  our
product candidates.

If we fail to correctly identify or interpret relevant patents, we may be subject to infringement claims. We cannot
guarantee that we will be able to successfully settle or otherwise resolve such infringement claims. If we fail in any such
dispute,  in  addition  to  being  forced  to  pay  monetary  damages,  we  may  be  temporarily  or  permanently  prohibited  from
commercializing  our  product  candidates.  We  might,  if  possible,  also  be  forced  to  redesign  our  product  candidates  in  a
manner that no longer infringes third-party intellectual property rights. Any of these events, even if we were ultimately to
prevail,  could  require  us  to  divert  substantial  financial  and  management  resources  that  we  would  otherwise  be  able  to
devote to our business.

Changes in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing
our ability to protect our product candidates.

Obtaining and enforcing patents in the biotechnology and genetic medicine industries involve both technological
complexity and legal complexity. In addition, the Leahy-Smith America Invents Act, or the AIA, which was passed in
September 2011, resulted in significant changes to the U.S. patent system.

An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned from a
“first-to-invent” to a “first-to-file” system for deciding which party should be granted a patent when two or more patent
applications are filed by different parties claiming the same invention. Under a “first-to-file” system, assuming the other
requirements for patentability are met, the first inventor to file a patent application generally will be entitled to a patent on
the  invention  regardless  of  whether  another  inventor  had  made  the  invention  earlier.  A  third  party  that  files  a  patent
application in the USPTO after that date but before us could therefore be awarded a patent covering an invention of ours
even if we made the invention before it was made by the third party. This will require us to be cognizant of the time from
invention  to  filing  of  a  patent  application  and  diligent  in  filing  patent  applications,  but  circumstances  could  prevent  us
from promptly filing patent applications on our inventions.

In addition, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not
have  been  invalidated  if  first  challenged  by  the  third  party  as  a  defendant  in  a  district  court  action  because  of  a  lower
evidentiary  standard  in  USPTO  proceedings  compared  to  the  evidentiary  standard  in  U.S.  federal  courts  necessary  to
invalidate a patent claim. An adverse determination in any such proceeding could reduce the scope of, or invalidate, our
owned or in-licensed patent rights, allow third parties to commercialize our technology or products and compete directly
with  us,  without  payment  to  us,  or  result  in  our  inability  to  manufacture  or  commercialize  products  without  infringing
third-party patent rights.

Additionally, the U.S. Supreme Court has ruled on several patent cases in recent years either narrowing the scope
of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations, and
there  are  other  open  questions  under  patent  law  that  courts  have  yet  to  decisively  address.  In  addition  to  increasing
uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty
with  respect  to  the  value  of  patents,  once  obtained.  Depending  on  decisions  by  Congress,  the  federal  courts  and  the
USPTO, the laws and regulations governing patents could change in unpredictable ways and could weaken our ability to
obtain  new  patents  or  to  enforce  our  existing  patents  and  patents  that  we  might  obtain  in  the  future.  In  addition,  the
European patent system is relatively stringent in the type of amendments that are allowed during prosecution, but, the

90

Table of Contents

complexity and uncertainty of European patent laws has also increased in recent years. Complying with these laws and
regulations could limit our ability to obtain new patents that may be important for our business.

We enjoy only limited geographical protection with respect to certain patents and we may not be able to protect
our intellectual property rights throughout the world.

Filing, prosecuting and defending patents covering our product candidates in all countries throughout the world
would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be
less  extensive  than  those  in  the  United  States.  In-licensing  patents  covering  our  product  candidates  in  all  countries
throughout the world may similarly be prohibitively expensive, if such opportunities are available at all. And in- licensing
or filing, prosecuting and defending patents even in only those jurisdictions in which we develop or commercialize our
product  candidates  may  be  prohibitively  expensive  or  impractical.  Competitors  may  use  our  and  our  licensors’
technologies  in  jurisdictions  where  we  have  not  obtained  patent  protection  or  licensed  patents  to  develop  their  own
products  and,  further,  may  export  otherwise  infringing  products  to  territories  where  we  and  our  licensors  have  patent
protection, but enforcement is not as strong as that in the United States, the UK or the EU. These products may compete
with our product candidates, and our or our licensors’ patents or other intellectual property rights may not be effective or
sufficient to prevent them from competing.

The  laws  of  some  jurisdictions  do  not  protect  intellectual  property  rights  to  the  same  extent  as  the  laws  or
regulations  in  the  United  States,  the  UK  and  the  EU,  and  many  companies  have  encountered  significant  difficulties  in
protecting  and  defending  proprietary  rights  in  such  jurisdictions.  Moreover,  the  legal  systems  of  certain  countries,
particularly  certain  developing  countries,  do  not  favor  the  enforcement  of  patents,  trade  secrets  or  other  forms  of
intellectual  property,  which  could  make  it  difficult  for  us  to  prevent  competitors  in  some  jurisdictions  from  marketing
competing  products  in  violation  of  our  proprietary  rights  generally.  Proceedings  to  enforce  our  patent  rights  in  foreign
jurisdictions, whether or not successful, are likely to result in substantial costs and divert our efforts and attention from
other  aspects  of  our  business,  and  additionally  could  put  at  risk  our  or  our  licensors’  patents  of  being  invalidated  or
interpreted  narrowly,  could  increase  the  risk  of  our  or  our  licensors’  patent  applications  not  issuing,  or  could  provoke
third  parties  to  assert  claims  against  us.  We  may  not  prevail  in  any  lawsuits  that  we  initiate,  while  damages  or  other
remedies may be awarded to the adverse party, which may be commercially significant. If we prevail, damages or other
remedies  awarded  to  us,  if  any,  may  not  be  commercially  meaningful.  Accordingly,  our  efforts,  or  the  efforts  of  our
licensors  or  collaborators,  to  enforce  intellectual  property  rights  around  the  world  may  be  inadequate  to  obtain  a
significant commercial advantage from the intellectual property that we develop or license.

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate
amount of time.

The term of any individual patent depends on applicable law in the country where the patent is granted. In the
United States, provided all maintenance fees are timely paid, a patent generally has a term of 20 years from its application
filing date or earliest claimed non-provisional filing date. Extensions may be available under certain circumstances, but
the life of a patent and, correspondingly, the protection it affords is limited. Even if we or our licensors obtain patents
covering  our  product  candidates,  when  the  terms  of  all  patents  covering  a  product  expire,  our  business  may  become
subject to competition from competitive medications, including generic medications. Given the amount of time required
for  the  development,  testing  and  regulatory  review  and  approval  of  new  product  candidates,  patents  protecting  such
candidates may expire before or shortly after such candidates are commercialized. As a result, our owned and licensed
patent  portfolio  may  not  provide  us  with  sufficient  rights  to  exclude  others  from  commercializing  products  similar  or
identical to ours.

91

Table of Contents

If  we  do  not  obtain  patent  term  extension  in  the  United  States  under  the  Hatch-Waxman  Act  and  in  foreign
countries under similar legislation, thereby potentially extending the term of marketing exclusivity for our product
candidates, our business may be harmed.

In the United States, a patent that covers an FDA-approved drug or biologic may be eligible for a term extension
designed to restore the period of the patent term that is lost during the premarket regulatory review process conducted by
the FDA. Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one
or  more  of  our  U.S.  patents  may  be  eligible  for  limited  patent  term  extension  under  the  Drug  Price  Competition  and
Patent  Term  Restoration  Act  of  1984,  or  the  Hatch-Waxman  Act,  which  permits  a  patent  term  extension  of  up  to  five
years  for  a  patent  covering  an  approved  product  as  compensation  for  effective  patent  term  lost  during  product
development and the FDA regulatory review process. In the UK and the EU, our product candidates may be eligible for
term extensions based on similar legislation. In each of these jurisdictions, however, we may not receive an extension if
we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy
applicable  requirements.  Even  if  we  are  granted  such  extension,  the  duration  of  such  extension  may  be  less  than  our
request. If we are unable to obtain a patent term extension, or if the term of any such extension is less than our request,
the  period  during  which  we  can  enforce  our  patent  rights  for  that  product  will  be  essentially  shortened  and  our
competitors  may  obtain  approval  to  market  competing  products  sooner.  The  resulting  reduction  in  revenue  from
applicable products could be substantial.

Our proprietary rights may not adequately protect our technologies and product candidates, and do not
necessarily address all potential threats to our competitive advantage.

The  degree  of  future  protection  afforded  by  our  intellectual  property  rights  is  uncertain  because  intellectual
property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive
advantage. The following examples are illustrative:

● others may be able to make products that are the same as or similar to our product candidates but that

are not covered by the claims of the patents that we own or have exclusively licensed;

● others,  including  inventors  or  developers  of  our  owned  or  in-licensed  patented  technologies  who  may
become  involved  with  competitors,  may  independently  develop  similar  technologies  that  function  as
alternatives  or  replacements  for  any  of  our  technologies  without  infringing  our  intellectual  property
rights;

● we  or  our  licensors  or  our  other  collaboration  partners  might  not  have  been  the  first  to  conceive  and
reduce to practice the inventions covered by the patents or patent applications that we own, license or
will own or license;

● we  or  our  licensors  or  our  other  collaboration  partners  might  not  have  been  the  first  to  file  patent
applications covering certain of the patents or patent applications that we or they own or have obtained a
license, or will own or will have obtained a license;

● we or our licensors may fail to meet obligations to the U.S. government with respect to in-licensed

patents and patent applications funded by U.S. government grants, leading to the loss of patent rights;

● issued patents that we own or exclusively license may not provide us with any competitive advantage, or

may be held invalid or unenforceable, as a result of legal challenges by our competitors; and

● our competitors might conduct research and development activities in countries where we do not have
patent rights, or in countries where research and development safe harbor laws exist, and then use the

92

Table of Contents

information  learned  from  such  activities  to  develop  competitive  products  for  sale  in  our  major
commercial markets.

Our  reliance  on  third  parties  may  require  us  to  share  our  trade  secrets,  which  increases  the  possibility  that  our
trade secrets will be misappropriated or disclosed, and confidentiality agreements with employees and third parties
may not adequately prevent disclosure of trade secrets and protect other proprietary information.

We  consider  proprietary  trade  secrets,  confidential  know-how  and  unpatented  know-how  to  be  important  to  our
business.  We  may  rely  on  trade  secrets  and  confidential  know-how  to  protect  our  technology,  especially  where  patent
protection  is  believed  by  us  to  be  of  limited  value.  However,  trade  secrets  and  confidential  know-how  are  difficult  to
protect, and we have limited control over the protection of trade secrets and confidential know-how used by our licensors,
collaborators and suppliers. Because we have relied in the past on third parties to manufacture our product candidates,
because  we  may  continue  to  do  so  in  the  future,  and  because  we  expect  to  collaborate  with  third  parties  on  the
development  of  our  current  product  candidates  and  any  future  product  candidates  we  develop,  we  may,  at  times,  share
trade  secrets  with  them.  We  also  conduct  joint  research  and  development  programs  that  may  require  us  to  share  trade
secrets under the terms of our research and development partnerships or similar agreements. Under such circumstances,
trade secrets and confidential know-how can be difficult to maintain as confidential.

To protect this type of information against disclosure or appropriation by competitors, our policy is to require our
employees,  consultants,  contractors  and  advisors  to  enter  into  confidentiality  agreements  and,  if  applicable,  material
transfer agreements, consulting agreements or other similar agreements with us prior to beginning research or disclosing
proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential
information,  including  our  trade  secrets.  However,  current  or  former  employees,  consultants,  contractors  and  advisers
may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may
not  provide  an  adequate  remedy  in  the  event  of  unauthorized  disclosure  of  confidential  information.  We  may  also  be
subject  to  claims  that  our  employees,  consultants  or  independent  contractors  have  wrongfully  used  or  disclosed
confidential  information  of  their  former  employers  or  other  third  parties.  The  need  to  share  trade  secrets  and  other
confidential  information  increases  the  risk  that  such  trade  secrets  become  known  by  our  competitors,  are  inadvertently
incorporated  into  the  technology  of  others,  or  are  disclosed  or  used  in  violation  of  these  agreements.  Given  that  our
competitive position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or
other  unauthorized  use  or  disclosure  would  impair  our  competitive  position  and  may  have  an  adverse  effect  on  our
business and results of operations. Enforcing a claim that a third party obtained illegally and is using trade secrets and/or
confidential  know-how  is  expensive,  time  consuming  and  unpredictable,  and  the  enforceability  of  confidentiality
agreements  may  vary  from  jurisdiction  to  jurisdiction.  Courts  outside  the  United  States  are  sometimes  less  willing  to
protect proprietary information, technology and know-how.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition
in our markets of interest and our business may be adversely affected.

If  our  trademarks  and  trade  names  are  not  adequately  protected,  then  we  may  not  be  able  to  build  name
recognition  in  our  markets  of  interest  and  our  business  may  be  adversely  affected.  Our  trademark  MeiraGTx  has  been
registered  in  the  EU,  UK  and  United  States.  We  may  not  be  able  to  protect  our  rights  to  these  trademarks  and  trade
names, which we need to build name recognition among potential partners or customers in our markets of interest. At
times,  competitors  may  adopt  trade  names  or  trademarks  similar  to  ours,  thereby  impeding  our  ability  to  build  brand
identity  and  possibly  leading  to  market  confusion.  In  addition,  there  could  be  potential  trade  name  or  trademark
infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our
unregistered trademarks or trade names. Over the long term, if we are unable to successfully register our trademarks and
trade  names  and  establish  name  recognition  based  on  our  trademarks  and  trade  names,  then  we  may  not  be  able  to
compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights
related to trademarks, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could

93

Table of Contents

result  in  substantial  costs  and  diversion  of  resources  and  could  adversely  impact  our  financial  condition  or  results  of
operations.

We may need to license or acquire additional intellectual property from third parties, and such intellectual property
may not be available or may not be available on commercially reasonable terms.

The growth of our business may depend in part on our ability to acquire or in-license additional proprietary rights.
For  example,  our  programs  may  involve  product  candidates  or  equipment  that  may  require  the  use  of  additional
proprietary rights held by third parties. Our product candidates may also require specific formulations to work effectively
and  efficiently.  These  formulations  may  be  covered  by  intellectual  property  rights  held  by  others.  We  may  develop
products containing our compositions and pre-existing pharmaceutical compositions. These pharmaceutical products may
be covered by intellectual property rights held by others. We may be required by the FDA, MHRA, EMA or other foreign
regulatory authorities to provide a companion diagnostic test or tests with our product candidates. These diagnostic test or
tests may be covered by intellectual property rights held by others. We may be unable to acquire or in-license any relevant
third-party intellectual property rights that we identify as necessary or important to our business operations. We may fail
to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all, which would harm our business. We
may need to cease use of the compositions or methods covered by such third-party intellectual property rights, and may
need to seek to develop alternative approaches that do not infringe on such intellectual property rights which may entail
additional costs and development delays, even if we were able to develop such alternatives, which may not be feasible.
Even if we are able to obtain a license under such intellectual property rights, any such license may be non-exclusive,
which may allow our competitors access to the same technologies licensed to us.

Risks Related to Employee Matters and Managing Growth

We may need to expand our organization, and we may experience difficulties in managing this growth, which
could disrupt our operations.

As of December 31, 2022, we had 358 employees. We expect to continue to expand our organization, including
hiring  and  training  employees  and  managerial  personnel  to  staff  our  expanding  manufacturing  and  supply  chain
operations  in  our  new  facilities  in  Ireland.  We  may  have  difficulty  identifying,  hiring  and  integrating  new  personnel.
Future  growth  would  impose  significant  additional  responsibilities  on  our  management,  including  the  need  to  identify,
recruit, maintain, motivate and integrate additional employees, consultants and contractors. Also, our management may
need  to  divert  a  disproportionate  amount  of  its  attention  away  from  our  day-to-day  activities  and  devote  a  substantial
amount  of  time  to  managing  these  growth  activities.  We  may  not  be  able  to  effectively  manage  the  expansion  of  our
operations,  which  may  result  in  weaknesses  in  our  infrastructure,  give  rise  to  operational  mistakes,  loss  of  business
opportunities,  loss  of  employees  and  reduced  productivity  among  remaining  employees.  Our  expected  growth  could
require significant capital expenditures and may divert financial resources from other projects, such as the development
of product candidates. If our management is unable to effectively manage our growth, our expenses may increase more
than expected, our ability to generate and/or grow revenues could be reduced, and we may not be able to implement our
business strategy. Our future financial performance and our ability to commercialize our product candidates and compete
effectively  will  depend,  in  part,  on  our  ability  to  effectively  manage  any  future  growth.  Our  expected  growth  could
require significant capital expenditures and may divert financial resources from other projects, such as the development
of additional product candidates. If our management is unable to effectively manage our expected growth, our expenses
may increase more than expected, our potential ability to generate revenue could be reduced and we may not be able to
implement our business strategy. Many of the biotechnology companies that we compete against for qualified personnel
and consultants have greater financial and other resources, different risk profiles and a longer history in the industry than
we do. If we are unable to continue to attract and retain high-quality personnel and consultants, the rate and success at
which we can discover and develop product candidates and operate our business will be limited.

Our future success depends on our ability to retain our key personnel and to attract, retain and motivate
qualified personnel.

Our  industry  has  experienced  a  high  rate  of  turnover  of  management  personnel  in  recent  years.  We  are  highly
dependent on the development, regulatory, commercialization and business development expertise of Alexandria Forbes,
Ph.D., our President and Chief Executive Officer, Rich Giroux, our Chief Operating Officer and Chief Financial Officer
and  Stuart  Naylor,  Ph.D.,  our  Chief  Development  Officer,  as  well  as  the  other  principal  members  of  our  management,
scientific  and  clinical  teams.  Although  we  have  formal  employment  agreements  with  certain  of  our  executive  officers,
these  agreements  do  not  prevent  them  from  terminating  their  employment  with  us  at  any  time  and,  for  certain  of  our
executive  officers,  entitle  them  to  receive  severance  payments  in  connection  with  their  voluntary  resignation  of
employment.

If we lose one or more of our executive officers or key employees, our ability to implement our business strategy
successfully  could  be  seriously  harmed.  Furthermore,  replacing  executive  officers  and  key  employees  may  be  difficult
and may take an extended period of time because of the limited number of individuals in our industry with the breadth of
skills and experience required to develop, gain regulatory approval of and commercialize product candidates successfully.
Competition  to  hire  from  this  limited  pool  is  intense,  and  we  may  be  unable  to  hire,  train,  retain  or  motivate  these
additional key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology
companies  for  similar  personnel.  In  addition,  we  rely  on  consultants  and  advisors,  including  scientific  and  clinical
advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and
advisors  may  be  engaged  by  entities  other  than  us  and  may  have  commitments  under  consulting  or  advisory  contracts
with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality
personnel, our ability to develop and commercialize product candidates will be limited.

Potential product liability lawsuits against us could cause us to incur substantial liabilities and limit
commercialization of any products that we may develop.

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing
approval  exposes  us  to  the  risk  of  product  liability  claims.  Product  liability  claims  might  be  brought  against  us  by
consumers, health care providers, pharmaceutical companies or others selling or otherwise coming into contact with our
products.  On  occasion,  large  judgments  have  been  awarded  in  class  action  lawsuits  based  on  products  that  had
unanticipated adverse effects. If we cannot successfully defend against product liability claims, we could incur substantial
liability and costs. In addition, regardless of merit or eventual outcome, product liability claims may result in:

● impairment of our business reputation and significant negative media attention;

● withdrawal of participants from our clinical trials;

● significant time, costs and diversion of management resources to defend the related litigation;

● substantial monetary awards to patients or other claimants;

● inability to commercialize our product candidates;

● product recalls, withdrawals or labeling, marketing or promotional restrictions;

● decreased demand for our product candidates, if approved for commercial sale; and

● loss of revenue.

Our insurance policies are expensive and protect us only from some business risks, which leaves us exposed
to significant uninsured liabilities.

We  do  not  carry  insurance  for  all  categories  of  risk  that  our  business  may  encounter.  Some  of  the  policies  we
currently maintain include general liability, clinical trial liability, employment practices liability, property, auto, workers’
compensation, umbrella, cyber and directors’ and officers’ insurance. Any additional product liability insurance coverage
we  acquire  in  the  future,  may  not  be  sufficient  to  reimburse  us  for  any  expenses  or  losses  we  may  suffer.  Moreover,
insurance coverage is becoming increasingly expensive and restrictive, and in the future we may not be able to maintain
insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. If we obtain
marketing approval for our product candidates, we intend to acquire insurance coverage to include the sale of commercial
products;  however,  we  may  be  unable  to  obtain  product  liability  insurance  on  commercially  reasonable  terms  or  in
adequate amounts. A successful product liability claim or series of claims brought against us could cause our share price
to decline and, if judgments exceed our insurance coverage, could adversely affect our results of operations and business,
including preventing or limiting the commercialization of any product candidates we develop. We do not carry specific
biological  or  hazardous  waste  insurance  coverage,  and  our  property,  casualty  and  general  liability  insurance  policies
specifically  exclude  coverage  for  damages  and  fines  arising  from  biological  or  hazardous  waste  exposure  or
contamination. Accordingly, in the event of contamination or injury, we could be held liable for damages or be penalized
with fines in an amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended.

Operating as a public company may make it more difficult and more expensive for us to obtain director and officer
liability  insurance,  and  we  may  be  required  to  accept  reduced  policy  limits  and  coverage  or  incur  substantially  higher
costs  to  obtain  the  same  or  similar  coverage.  As  a  result,  it  may  be  more  difficult  for  us  to  attract  and  retain  qualified
people  to  serve  on  our  board  of  directors,  our  board  committees  or  as  executive  officers.  If  we  are  unable  to  maintain
existing insurance with adequate levels of coverage, any significant uninsured liability may require us to pay substantial
amounts, which would adversely affect our cash position and results of operations.

Our employees and independent contractors, including consultants, vendors, and any third parties we may engage in
connection with development and commercialization may engage in misconduct or other improper activities,
including noncompliance with regulatory standards and requirements, which could harm our business.

Misconduct by our employees and independent contractors, including consultants, vendors, and any third parties
we may engage in connection with development and commercialization, could include intentional, reckless or negligent
conduct or unauthorized activities that violate: (i) applicable laws and regulations of the FDA, MHRA, EMA and other
regulatory  or  governmental  authorities,  including  those  laws  that  require  the  reporting  of  true,  complete  and  accurate
information  to  such  authorities;  (ii)  manufacturing  standards;  (iii)  data  privacy,  security,  fraud  and  abuse  and  other
healthcare  laws  and  regulations;  or  (iv)  laws  that  require  the  reporting  of  true,  complete  and  accurate  financial
information and data. Specifically, sales, marketing and business arrangements in the healthcare industry are subject to
extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices.
These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales
commission,  customer  incentive  programs  and  other  business  arrangements.  Activities  subject  to  these  laws  could  also
involve  the  improper  use  or  misrepresentation  of  information  obtained  in  the  course  of  clinical  trials,  creation  of
fraudulent data in preclinical studies or clinical trials or illegal misappropriation of drug product, which could result in
regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct
by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective
in  controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental  investigations  or  other
actions or lawsuits stemming from a failure to comply with such laws or regulations. Additionally, we are subject to the
risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions
are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have
a significant impact on our business and results of operations, including the imposition of significant civil, criminal and
administrative  penalties,  damages,  monetary  fines,  disgorgements,  possible  exclusion  from  participation  in  Medicare,
Medicaid, other U.S. federal healthcare programs or healthcare programs in other jurisdictions, integrity oversight and

reporting  obligations  to  resolve  allegations  of  non-compliance,  individual  imprisonment,  other  sanctions,  contractual
damages, reputational harm, diminished profits and future earnings, and curtailment of our operations.

Our business and operations may suffer in the event of system failures and our systems and those of our business
partners and service providers may be vulnerable to cybersecurity risks.

Our information technology systems, including manufacturing systems, as well as those of our business partners
and  service  providers,  are  vulnerable  to  damage  from  computer  viruses,  unauthorized  access,  hardware  and  software
failures, natural disasters, terrorism, war and telecommunication and electrical failures. If such an event were to occur, it
could  result  in  a  material  disruption  of  our  product  candidate  development  programs  or  manufacturing  operations.  For
example, the loss of preclinical study or clinical trial data from completed, ongoing or planned trials could result in delays
in  our  regulatory  approval  efforts  and  significantly  increase  our  costs  to  recover  or  reproduce  the  data.  A  significant
interruption to our manufacturing operations could delay the completion of clinical trials and increase the costs of those
trials. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications,
or inappropriate disclosure of personal, confidential or proprietary information, we could incur liability and the further
development of our product candidates could be delayed.

In  the  ordinary  course  of  our  business,  we,  our  business  partners  and  our  service  providers  collect,  process  and
store sensitive data, including intellectual property, clinical trial data, proprietary business information, personal data and
personally identifiable information of our clinical trial subjects and employees. The secure processing, maintenance and
transmission  of  this  information  is  critical  to  our  operations.  Increased  cybersecurity  threats  pose  a  risk  to  this
information,  in  addition  to  our  and  our  business  partners’  and  service  providers’  systems  and  networks.  Attacks  upon
information technology systems are increasing in their frequency, levels of persistence, sophistication and intensity, and
are being conducted by sophisticated and organized groups, governments and individuals with a wide range of motives
and expertise. We may also face increased cybersecurity risks due to our reliance on internet technology and the number
of  our  employees  who  are  working  remotely,  which  may  create  additional  opportunities  for  cybercriminals  to  exploit
vulnerabilities. Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change
frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or
implement adequate preventative measures. We may also experience security breaches that may remain undetected for an
extended period. Even if identified, we may be unable to adequately investigate or remediate incidents or breaches due to
attackers  increasingly  using  tools  and  techniques  that  are  designed  to  circumvent  controls,  to  avoid  detection,  and  to
remove or obfuscate forensic evidence.

Despite our security measures, our information technology and infrastructure may be vulnerable to cyber-attacks
by  hackers  or  internal  bad  actors,  or  breached  due  to  employee  error,  a  technical  vulnerability,  malfeasance  or  other
disruptions  that  could  have  a  negative  impact,  including  loss  or  destruction  of  data  (including  confidential  or  critical
business information). Although, to our knowledge, we have not experienced any such material security breach to date,
we  may  experience  cybersecurity  incidents  such  as  malware  infections,  ransomware,  phishing  attempts,  thefts  of
personal,  confidential,  proprietary  or  other  critical  business  information  and  other  attempts  at  compromising  our
information technology that are typical for a company of our size in our market. Any security breach could compromise
our  networks  and  the  information  stored  there  could  be  accessed,  publicly  disclosed,  lost  or  stolen.  Any  such  access,
disclosure  or  other  loss  of  information  could  result  in  legal  claims  or  proceedings,  liability  under  laws  that  protect  the
privacy of personal information, significant regulatory penalties, and such an event could disrupt our operations, damage
our reputation, result in significant expenses in implementing future security measures and cause a loss of confidence in
us and our ability to conduct clinical trials, which could adversely affect our reputation and financial results, and delay
clinical development of our product candidates.

The UK’s withdrawal from the EU has resulted in changes to regulatory requirements and has had and may continue
to have a negative effect on global economic conditions, financial markets and our business, which could reduce the
price of our shares.

Following  a  national  referendum  and  enactment  of  legislation  by  the  government  of  the  UK,  the  UK  formally
withdrew  from  the  EU  on  January  31,  2020,  commonly  referred  to  as  “Brexit”.  Since  the  end  of  the  Brexit  transition
period  on  January  1,  2021,  Great  Britain  (England,  Scotland  and  Wales)  has  not  been  directly  subject  to  EU  laws,
however under the terms of the Protocol on Ireland and Northern Ireland, EU laws have generally applied to Northern
Ireland. On February 27, 2023, the UK Government and the European Commission reached a political agreement on the
“Windsor  Agreement”  which  may  revise  the  Protocol  on  Ireland  and  Northern  Ireland  in  order  to  address  some  of  the
perceived shortcomings in its operation. Under the proposed changes, Northern Ireland would be reintegrated under the
regulatory authority of the MHRA with respect to medicinal products. These proposed changes need to be codified and
agreed by the respective parliaments of the UK and EU before taking effect. There could be additional uncertainty and
risk around what these changes will mean to our business.

More generally, it is currently unclear to what extent the UK Government will seek to align its regulations with the
EU.  The  EU  laws  that  have  been  transposed  into  UK  law  through  secondary  legislation  remain  applicable  in  Great
Britain.  However,  under  the  Retained  EU  Law  (Revocation  and  Reform)  Bill  2022,  which  is  currently  before  the  UK
parliament, any retained EU law not expressly preserved and “assimilated” into domestic law or extended by ministerial
regulations (to no later than June 23, 2026) will automatically expire and be revoked by December 31, 2023. In addition,
new legislation such as the CTR is not applicable in Great Britain. Whilst the EU-UK Trade and Cooperation Agreement,
or TCA, includes the mutual recognition of Good Manufacturing Practice, or GMP inspections of manufacturing facilities
for  medicinal  products  and  GMP  documents  issued,  it  does  not  contain  wholesale  mutual  recognition  of  UK  and  EU
pharmaceutical regulations and product standards. There may be divergent local requirements in Great Britain from the
EU  in  the  future,  which  may  impact  clinical  and  development  activities  that  occur  in  the  UK  in  the  future.  Similarly,
clinical  trial  submissions  in  the  UK  will  not  be  able  to  be  bundled  with  those  of  EU  member  states  within  the  EMA
Clinical  Trial  Information  System,  or  CTIS,  adding  further  complexity,  cost  and  potential  risk  to  future  clinical  and
development activity in the UK.  Significant political and economic uncertainty remains about how much the relationship
between the UK and EU will differ as a result of the UK’s withdrawal.

These developments, or the perception that any related developments could occur, have had and may continue to
have  a  material  adverse  effect  on  global  economic  conditions  and  the  stability  of  global  financial  markets,  and  may
significantly  reduce  global  market  liquidity  and  restrict  the  ability  of  key  market  participants  to  operate  in  certain
financial  markets.  Any  of  these  factors  could  depress  economic  activity  and  restrict  our  access  to  capital,  which  could
have a material adverse effect on our business, financial condition and results of operations and reduce the price of our
ordinary shares.

Companies established in Great Britain cannot use the centralized procedure and instead must follow one of the
UK national authorization procedures or one of the remaining post-Brexit international cooperation procedures (such as
the Access Consortium) to obtain an MA to market products in Great Britain. The MHRA may rely on a decision taken
by the European Commission on the approval of a new (centralized procedure) MA when determining an application for
a Great Britain MA; or use the MHRA’s decentralized or mutual recognition procedures which enable MAs approved in
EU  member  states  (or  Iceland,  Liechtenstein,  Norway)  to  be  granted  in  Great  Britain.  Additionally,  the  ‘Unfettered
Access Procedure’ enables an MA holder in Northern Ireland to seek recognition in Great Britain.

The  full  impact  of  these  new  arrangements  and  requirements,  both  on  our  existing  processes  and  our  ability  to
adjust our business and operations to operate successfully in the UK and EU, as well as more broadly on UK-EU cross-
border trade and the economy, are expected to become clearer in the coming years. In particular, it remains to be seen
whether  the  initial  implementation  of,  and  adjustment  of  UK-EU  trading  processes  for,  the  TCA  could  disrupt  or
otherwise negatively impact our business and operations. These negative impacts could include amongst others a decrease
in foreign direct investment in the UK, an increase of our costs, disruption of our supply chains, restrictions on

98

Table of Contents

our ability to access capital and depression on economic activity or economic instability, which could in turn lead to a
reduction in asset valuations, currency exchange rates and credit ratings.

In addition, the TCA has imposed additional restrictions on the free movement of people between the UK and the
EU,  which  could  have  a  material  adverse  effect  on  us,  since  we  compete  in  these  jurisdictions  for  well  qualified
employees  in  all  aspects  of  our  business.  Any  impact  on  our  ability  to  attract  new  employees  and  to  retain  existing
employees in their current jurisdictions could decrease our competitiveness. Any of these factors could have an adverse
effect on our business, financial condition, results of operations, and prospects.

Risks Related to Our Ordinary Shares

The market price of our ordinary shares may be volatile and fluctuate substantially, which could result in
substantial losses for purchasers of our ordinary shares.

Our share price is likely to be volatile. The stock market in general and the market for smaller biopharmaceutical
companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of
particular  companies.  As  a  result  of  this  volatility,  you  may  not  be  able  to  sell  your  ordinary  shares  at  or  above  your
purchase price. The market price for our ordinary shares may be influenced by many factors, including:

● the success of competitive products or technologies;

● actual or expected changes in our growth rate relative to our competitors;

● results of clinical trials of our product candidates or those of our competitors;

● developments related to our existing or any future collaborations;

● regulatory or legal developments in the United States and other countries;

● development of new product candidates that may address our markets and make our product candidates

less attractive;

● changes in physician, hospital or healthcare provider practices that may make our product candidates

less useful;

● announcements by us, our partners or our competitors of significant acquisitions, strategic partnerships,

joint ventures, collaborations or capital commitments;

● developments or disputes concerning patent applications, issued patents or other proprietary rights;

● the recruitment or departure of key personnel;

● the level of expenses related to any of our product candidates or clinical development programs;

● failure to meet or exceed financial estimates and projections of the investment community or that we

provide to the public;

● the results of our efforts to discover, develop, acquire or in-license additional product candidates or

products;

99

Table of Contents

● actual or expected changes in estimates as to financial results, development timelines, recommendations

by securities analysts or shifting investor perceptions;

● variations in our financial results or those of companies that are perceived to be similar to us;

● changes in the structure of healthcare payment systems;

● market conditions in the pharmaceutical and biotechnology sectors;

● general economic, industry and market conditions;

● changes in accounting principles; and

● the other factors described in this “Item 1A. Risk Factors” section and elsewhere in this Form 10-K.

In  addition,  the  stock  market  in  general,  and  Nasdaq  and  biopharmaceutical  companies  in  particular,  have  experienced
extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of
these  companies.  In  the  past,  when  the  market  price  of  a  security  has  been  volatile,  holders  of  that  security  have
sometimes  instituted  securities  class  action  litigation  against  the  issuer.  This  risk  is  especially  relevant  for  us  because
biopharmaceutical companies have experienced significant stock price volatility in recent years and during the COVID-19
pandemic. If any of the holders of our ordinary shares were to bring such a lawsuit against us, we could incur substantial
costs  defending  the  lawsuit  and  the  attention  of  our  senior  management  would  be  diverted  from  the  operation  of  our
business. Any adverse determination in litigation could also subject us to significant liabilities. Broad market and industry
factors may negatively affect the market price of our ordinary shares, as well as general economic, political and market
conditions  such  as  recessions,  interest  rate  changes  or  international  currency  fluctuations,  regardless  of  our  actual
operating performance. Further, a decline in the financial markets and related factors beyond our control may cause the
price of our ordinary shares to decline rapidly and unexpectedly. If the market price of our ordinary shares does not exceed
your purchase price, you may not realize any return on your investment in us and may lose some or all of your investment.

Our executive officers, directors and principal shareholders, if they choose to act together, have the ability
to significantly influence all matters submitted to shareholders for approval.

As  of  December  31,  2022,  our  executive  officers,  directors  and  shareholders  who  owned  more  than  5%  of  our
outstanding  ordinary  shares  and  their  respective  affiliates,  in  the  aggregate,  hold  ordinary  shares  representing
approximately  40.0%  of  our  outstanding  ordinary  shares.  In  addition,  in  connection  with  entering  into  the  Financing
Agreement, we issued to an affiliate of Perceptive Advisors, LLC, our largest shareholder that employs a director serving
on our board, warrants to purchase an aggregate of 700,000 of our ordinary shares.

As a result, if these shareholders choose to act together, they would be able to significantly influence all matters
submitted to our shareholders for approval, as well as our management and affairs. For example, these persons, if they
choose to act together, would significantly influence the election of directors, the composition of our management and
approval of any merger, consolidation, sale of all or substantially all of our assets or other business combination that other
shareholders may desire. Any of these actions could adversely affect the market price of our ordinary shares.

We are an “emerging growth company” and a “smaller reporting company,” and the reduced disclosure
requirements applicable to emerging growth companies and smaller reporting companies may make our ordinary
shares less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS
Act”),  and  may  remain  an  emerging  growth  company  until  the  last  day  of  the  fiscal  year  December  31,  2023,  which
represents the fifth year anniversary of our IPO. However, if certain events occur prior to the end of such five-year period,

100

Table of Contents

including if we become a “large accelerated filer,” our annual gross revenues exceed $1.07 billion or we issue more than
$1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to
the end of such five-year period. For so long as we remain an emerging growth company, we are permitted and intend to
rely  on  exemptions  from  certain  disclosure  requirements  that  are  applicable  to  other  public  companies  that  are  not
emerging growth companies. These exemptions include:

● reduced disclosure obligations relating to the presentation of financial statements in the “Management’s
Discussion and Analysis of Financial Condition and Results of Operations” disclosure in our periodic
reports filed with the SEC;

● not being required to comply with the auditor attestation requirements in the assessment of our internal

control over financial reporting;

● not  being  required  to  comply  with  any  requirement  that  may  be  adopted  by  the  Public  Company
Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s
report providing additional information about the audit and the financial statements;

● reduced disclosure obligations regarding executive compensation; and

● exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive  compensation

and shareholder approval of any golden parachute payments not previously approved.

In  addition,  the  JOBS  Act  provides  that  an  emerging  growth  company  can  take  advantage  of  an  extended
transition period for complying with new or revised accounting standards. This allows an emerging growth company to
delay the adoption of these accounting standards until they would otherwise apply to private companies. We have elected
to take advantage of this extended transition period.

We are also a smaller reporting company, and we will remain a smaller reporting company until the fiscal year
following  the  determination  that  our  voting  and  non-voting  ordinary  shares  held  by  non-affiliates  is  more  than  $250
million measured on the last business day of our second fiscal quarter, or our annual revenues are more than $100 million
during  the  most  recently  completed  fiscal  year  and  our  voting  and  non-voting  ordinary  shares  held  by  non-affiliates  is
more  than  $700  million  measured  on  the  last  business  day  of  our  second  fiscal  quarter.  Similar  to  emerging  growth
companies,  smaller  reporting  companies  are  able  to  provide  simplified  executive  compensation  disclosure,  are  exempt
from the auditor attestation requirements of Section 404, and have certain other reduced disclosure obligations, including,
among  other  things,  not  being  required  to  provide  selected  financial  data,  supplemental  financial  information  or  risk
factors.

We  may  choose  to  take  advantage  of  some,  but  not  all,  of  the  available  exemptions  for  emerging  growth
companies  and  smaller  reporting  companies.  We  cannot  predict  whether  investors  will  find  our  ordinary  shares  less
attractive if we rely on these exemptions. If some investors find our ordinary shares less attractive as a result, there may
be a less active trading market for our ordinary shares and our share price may be more volatile.

Anti-takeover  provisions  in  our  organizational  documents  and  Cayman  Islands  law  may  discourage  or  prevent  a
change of control, even if an acquisition would be beneficial to our shareholders, which could depress the price of our
ordinary shares and prevent attempts by our shareholders to replace or remove our current management.

Our  memorandum  and  articles  of  association  contain  provisions  that  may  discourage  unsolicited  takeover
proposals that shareholders may consider to be in their best interests. Our board of directors is divided into three classes
with staggered, three-year terms. Our board of directors has the ability to designate the terms of and issue preferred shares
without  shareholder  approval.  We  are  also  subject  to  certain  provisions  under  Cayman  Islands  law  that  could  delay  or
prevent a change of control. Together these provisions may make more difficult the removal of management and may

101

Table of Contents

discourage  transactions  that  otherwise  could  involve  payment  of  a  premium  over  prevailing  market  prices  for  our
ordinary shares.

There may be difficulties in enforcing foreign judgments against our management or us.

Certain of our directors and management reside outside the United States. A significant portion of our assets and
such persons’ assets are located outside the United States. As a result, it may be difficult or impossible for investors to
effect service of process upon us within the United States or other jurisdictions, including judgments predicated upon the
civil liability provisions of the federal securities laws of the United States.

In particular, investors should be aware that there is uncertainty as to whether the courts of the Cayman Islands or
any  other  applicable  jurisdictions  would  recognize  and  enforce  judgments  of  U.S.  courts  obtained  against  us  or  our
directors or management predicated upon the civil liability provisions of the securities laws of the United States or any
state in the United States or entertain original actions brought in the Cayman Islands or any other applicable jurisdiction’s
courts against us or our directors or officers predicated upon the securities laws of the United States or any state in the
United States.

The rights of our shareholders differ from the rights typically offered to shareholders of a U.S. corporation.

Our corporate affairs and the rights of holders of ordinary shares are governed by Cayman Islands law, including
the  provisions  of  the  Cayman  Islands  Companies  Act  (as  amended),  or  the  Companies  Act,  the  common  law  of  the
Cayman Islands and by our memorandum and articles of association. We are also subject to the federal securities laws of
the United States. The rights of shareholders to take action against the directors, actions by minority shareholders and the
fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common
law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial
precedent in the Cayman Islands as well as from English common law, the decisions of whose courts are of persuasive
authority,  but  are  not  binding  on  a  court  in  the  Cayman  Islands.  The  rights  of  our  shareholders  and  the  fiduciary
responsibilities  of  our  directors  under  Cayman  Islands  law  are  different  from  what  they  would  be  under  statutes  or
judicial  precedent  in  some  jurisdictions  in  the  United  States.  In  particular,  the  Cayman  Islands  has  a  different  body  of
securities laws as compared to the United States, and certain states, such as Delaware, may have more fully developed
and  judicially  interpreted  bodies  of  corporate  law.  In  addition,  Cayman  Islands  companies  may  not  have  standing  to
initiate a shareholders derivative action in a Federal court of the United States.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face
of actions taken by management, members of the board of directors or controlling shareholders than they would as public
shareholders of a United States company.

We expect to be treated as resident in the UK for tax purposes, but may be treated as a dual resident company for UK
tax purposes.

Our board of directors conducts our affairs so that the central management and control of the company is exercised
in the UK. As a result, we expect to be treated as resident in the UK for UK tax purposes. Accordingly, we expect to be
subject to UK taxation on our income and gains, except where an exemption applies.

However,  we  may  be  treated  as  a  dual  resident  company  for  UK  tax  purposes.  As  a  result,  our  right  to  claim
certain reliefs from UK tax may be restricted, and changes in law or practice in the UK could result in the imposition of
further restrictions on our right to claim UK tax reliefs.

We may be classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes,
which could result in adverse U.S. federal income tax consequences to U.S. investors in our ordinary shares.

Based  on  the  current  and  anticipated  value  of  our  assets,  including  goodwill,  and  the  current  and  anticipated
composition  of  our  income,  assets  and  operations,  we  do  not  believe  we  were  a  PFIC  for  the  taxable  year  ended  on
December 31, 2022, and do not expect to be a PFIC for the current taxable year. However, the application of the PFIC
rules is subject to uncertainty in several respects, and we cannot assure you that the U.S. Internal Revenue Service, or the
IRS, will not take a contrary position. Furthermore, a separate determination must be made after the close of each taxable
year  as  to  whether  we  are  a  PFIC  for  that  year.  Accordingly,  we  cannot  assure  you  that  we  were  not  a  PFIC  for  our
taxable year ended on December 31, 2022 or that we will not be a PFIC for our current taxable year or any future taxable
year. A non-U.S. company will be considered a PFIC for any taxable year if (i) at least 75% of its gross income is passive
income (including interest income), or (ii) at least 50% of the value of its assets (based on an average of the quarterly
values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive
income. The value of our assets generally is determined by reference to the market price of our ordinary shares, which
may fluctuate considerably. In addition, the composition of our income and assets is affected by how, and how quickly,
we spend any cash we raise. If we were to be classified as a PFIC for any taxable year during which a U.S. holder holds
our ordinary shares, certain materially adverse U.S. federal income tax consequences could apply to such U.S. holder.

If  a  United  States  person  is  treated  as  owning  at  least  10%  of  our  ordinary  shares,  such  holder  may  be  subject  to
adverse U.S. federal income tax consequences.

If a U.S. holder of our ordinary shares is treated as owning (directly, indirectly or constructively) at least 10% of
the value or voting power of our ordinary shares, such U.S. holder may be treated as a “United States shareholder” with
respect to each “controlled foreign corporation” in our group (if any). If our group includes one or more U.S. subsidiaries,
certain  of  our  non-U.S.  subsidiaries  could  be  treated  as  controlled  foreign  corporations  (regardless  of  whether  we  are
treated  as  a  controlled  foreign  corporation).  A  United  States  shareholder  of  a  controlled  foreign  corporation  may  be
required  to  report  annually  and  include  in  its  U.S.  taxable  income  its  pro  rata  share  of  “Subpart  F  income,”  “global
intangible low-taxed income” and investments in U.S. property by controlled foreign corporations, regardless of whether
we  make  any  distributions.  An  individual  that  is  a  United  States  shareholder  with  respect  to  a  controlled  foreign
corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United
States  shareholder  that  is  a  U.S.  corporation.  Failure  to  comply  with  these  reporting  obligations  may  subject  you  to
significant monetary penalties and may prevent the statute of limitations from starting with respect to your U.S. federal
income  tax  return  for  the  year  for  which  reporting  was  due.  We  cannot  provide  any  assurances  that  we  will  assist
investors in determining whether any of our non-U.S. subsidiaries is treated as a controlled foreign corporation or whether
such investor is treated as a United States shareholder with respect to any of such controlled foreign corporations. Further,
we  cannot  provide  any  assurances  that  we  will  furnish  to  any  United  States  shareholders  information  that  may  be
necessary to comply with the aforementioned reporting and tax payment obligations. U.S. holders of our ordinary shares
should  consult  their  tax  advisors  regarding  the  potential  application  of  these  rules  to  their  investment  in  our  ordinary
shares.

Changes in tax laws or challenges to our tax position could adversely affect our results of operations and
financial condition.

We  are  subject  to  complex  tax  laws  that  are  subject  to  change  or  differing  interpretations,  including  on  a
retroactive basis. Any such changes in tax laws, regulations and treaties, or the interpretation thereof, tax policy initiatives
and reforms under consideration and the practices of tax authorities in jurisdictions in which we operate could adversely
affect our tax position, including our effective tax rate or tax payments.

103

Table of Contents

We have significant U.S. federal and state net operating losses, or NOLs, and UK carryforward tax losses which we
may not be able to realize or which may be restricted under applicable law. We also benefit from certain tax incentive
regimes, such as research and development tax credits. Any adverse change to these regimes, the application thereof
or challenges to the tax position we have adopted under these rules could adversely affect our results of operations
and financial condition.

As of December 31, 2022, we had federal and state NOL carryforwards in the United States of $63.8 million and
$64.4 million, respectively, and cumulative carryforward tax losses in the UK of $187.9 million, which we expect to be
available  to  reduce  future  taxable  income  subject  to  any  relevant  restrictions  (including  those  in  the  U.S.  and  UK  that
limit the percentage of taxable income that can be reduced by NOLs and carried forward losses). The U.S. federal and
state NOLs incurred prior to January 1, 2018 in the amount of approximately $1.0 million and $0.8 million, respectively,
will begin to expire in 2036. U.S. federal NOLs generated after December 31, 2017 are not subject to expiration but such
NOLs may only offset 80% of taxable income for taxable years beginning after December 31, 2020. As of December 31,
2022,  we  also  had  orphan  drug  and  research  and  development  credits  in  the  U.S.  in  the  amount  of  $9.4  million  and
research and development credits in the UK of $2.4 million. The UK carryforward tax losses will continue indefinitely,
subject to relevant restrictions, under current UK legislation.

The  NOLs  and  carryforward  tax  losses  are  subject  to  review  and  possible  adjustment  by  the  applicable  tax
authorities. Additionally, NOLs and UK carryforward tax losses, and research and development tax credits, may become
subject to limitations in the event of certain cumulative changes in the ownership interest of significant shareholders, as
determined under Sections 382 of the United States Internal Revenue Code, as well as the Corporation Tax Act 2010 Part
14 under the UK tax rules. This could limit the amount of NOLs or carryforward tax losses that we can utilize annually to
offset  future  taxable  income  or  tax  liabilities.  We  have  conducted  a  review  of  changes  in  the  ownership  interest  of
significant shareholders and determined that as of December 31, 2021, there were no limitations in the UK. However, for
U.S. federal tax purposes, we have determined that ownership changes occurred in August 2016 and June 2018. We are
still  in  the  process  of  determining  the  annual  limitation  on  NOLs  as  a  result  of  such  ownership  changes.  Subsequent
ownership  changes  and  changes  to  the  U.S.  federal  or  state  or  UK  tax  rules  in  respect  of  the  utilization  of  NOLs  and
carryforward tax losses may further affect the limitation in future years.

General Risk Factors

We may engage in acquisitions that could disrupt our business, cause dilution to our shareholders or reduce our
financial resources.

We have, and may in the future, enter into transactions to acquire other businesses, products or technologies. If
we  do  identify  suitable  candidates,  we  may  not  be  able  to  make  such  acquisitions  on  favorable  terms,  or  at  all.  Any
acquisitions we make may not strengthen our competitive position, and these transactions may be viewed negatively by
customers  or  investors.  We  may  decide  to  incur  debt  in  connection  with  an  acquisition  or  issue  our  ordinary  shares  or
other equity securities to the shareholders of the acquired company, which would reduce the percentage ownership of our
existing shareholders. We could incur losses resulting from undiscovered liabilities of the acquired business that are not
covered by the indemnification we may obtain from the seller. In addition, we may not be able to successfully integrate
the acquired personnel, technologies and operations into our existing business in an effective, timely and nondisruptive
manner. Acquisitions may also divert management attention from day-to-day responsibilities, increase our expenses and
reduce  our  cash  available  for  operations  and  other  uses.  We  cannot  predict  the  number,  timing  or  size  of  future
acquisitions or the effect that any such transactions might have on our operating results.

Exchange rate fluctuations may adversely affect our results of operations and financial condition.

Owing  to  the  international  scope  of  our  operations,  fluctuations  in  exchange  rates  may  adversely  affect  us,
particularly between the U.S. dollar on the one hand, and the pound sterling and euro on the other hand. As a result, our
business and the market price of our securities may be affected by such fluctuations, which may have a significant impact

104

Table of Contents

on our results of operations and cash flows from period to period. Currently, we do not have any exchange rate hedging
arrangements in place.

Our management team has broad discretion as to the use of the net proceeds from public and private equity or debt
financings and the investment of these proceeds may not yield a favorable return. We may invest the proceeds in ways
with which our shareholders disagree.

We have broad discretion in the application of any net proceeds we have received in the past or may receive in
the future pursuant to existing or future equity and debt financings. Shareholders may not agree with our decisions, and
our use of the proceeds and our existing cash and cash equivalents may not improve our results of operation or enhance
the  value  of  our  ordinary  shares.  Our  ability  to  apply  certain  proceeds  may  be  restricted.    For  example,  the  proceeds
provided  under  our  Note  Purchase  Agreement  may  be  used  for  working  capital  and  general  corporate  purposes.    Our
failure to apply any such funds effectively could have a material adverse effect on our business, delay the development of
our product candidates and cause the market price of our ordinary shares to decline. In addition, until the net proceeds are
used, they may be placed in investments that do not produce significant income or that may lose value. Additionally, our
existing cash and cash equivalents are subject to general credit, liquidity, market and interest rate risks, which have been
and may, in the future, be exacerbated by a U.S. and/or global financial crises. We may realize losses in the fair value of
certain  of  our  investments  or  a  complete  loss  of  these  investments  if  the  credit  markets  tighten,  which  would  have  an
adverse effect on our results of operations, liquidity and financial condition.

We incur substantial costs as a result of operating as a public company, and our management is required to devote
substantial time to new compliance initiatives and corporate governance practices.

As  a  public  company,  and  particularly  if  we  no  longer  qualify  as  an  emerging  growth  company  and  smaller
reporting company in the future, we incur and will continue to incur significant legal, accounting and other expenses that
we  did  not  incur  as  a  private  company.  The  Sarbanes-Oxley  Act  of  2002,  the  Dodd-Frank  Wall  Street  Reform  and
Consumer  Protection  Act,  The  Nasdaq  Global  Select  listing  requirements  and  other  applicable  securities  rules  and
regulations  impose  various  requirements  on  public  companies,  including  establishment  and  maintenance  of  effective
disclosure  and  financial  controls  and  corporate  governance  practices.  Our  management  and  other  personnel  need  to
devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations increase our
legal and financial compliance costs.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we are required to furnish a report by
our  management  on  our  internal  control  over  financial  reporting.  However,  while  we  remain  an  emerging  growth
company, we will not be required to include an attestation report on internal control over financial reporting issued by our
independent  registered  public  accounting  firm.  To  achieve  compliance  with  Section  404,  we  engage  in  a  process  to
document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard,
we will need to continue to dedicate internal resources, potentially engage outside consultants, adopt a detailed work plan
to  assess  and  document  the  adequacy  of  internal  control  over  financial  reporting,  continue  steps  to  improve  control
processes as appropriate, validate through testing whether such controls are functioning as documented, and implement a
continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a
risk  that  we,  or  our  independent  registered  public  accounting  firm  if  we  no  longer  qualify  as  an  emerging  growth
company, will not be able to conclude that our internal control over financial reporting is effective as required by Section
404.  In  addition,  any  testing  by  us  conducted  in  connection  with  Section  404,  or  any  subsequent  testing  by  our
independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting
that  are  deemed  to  be  material  weaknesses  or  that  may  require  prospective  or  retroactive  changes  to  our  financial
statements or identify other areas for further attention or improvement. If we identify one or more material weaknesses or
determine we have inadequate internal controls, it could result in an adverse reaction in the financial markets due to a loss
of confidence in the reliability of our financial statements.

If securities or industry analysts cease to publish research or reports about our business, or if they issue an adverse or
misleading opinion regarding our ordinary shares, our share price and trading volume could decline.

The trading market for our ordinary shares relies in part on the research and reports that industry or securities
analysts publish about us or our business. We do not control these analysts. Furthermore, if any of the analysts who cover
us  issue  an  adverse  or  misleading  opinion  regarding  us,  our  business  model,  our  intellectual  property  or  our  share
performance,  or  if  any  of  our  preclinical  studies  or  clinical  trials  and  operating  results  fail  to  meet  the  expectations  of
analysts, our share price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish
reports  on  us  regularly,  we  could  lose  visibility  in  the  financial  markets,  which  in  turn  could  cause  our  share  price  or
trading volume to decline.

Expectations relating to environmental, social and governance factors may impose additional costs and expose us to
new risks.

There is an increasing focus from the SEC, stock exchanges, certain investors and other stakeholders concerning
corporate responsibility, specifically related to environmental, social and governance factors. The SEC is considering and
in some cases has proposed rules regarding new disclosure requirements relating to environmental, social and governance
factors, and the SEC approved in 2021 new Nasdaq listing and disclosure requirements relating to board diversity that are
applicable  to  us.  Some  investors  may  use  these  factors  to  guide  their  investment  strategies  and,  in  some  cases,  may
choose not to invest in us if they believe our policies and disclosures relating to corporate responsibility are inadequate.
Third-party  providers  of  corporate  responsibility  ratings  and  reports  on  companies  have  varied  and  in  some  cases
inconsistent  standards.  In  addition,  the  criteria  by  which  companies’  corporate  responsibility  practices  are  assessed  are
evolving, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy such new
criteria. Alternatively, if we elect not to or are unable to satisfy such new criteria or do not meet the criteria of a specific
third-party  provider,  some  investors  may  conclude  that  our  policies  with  respect  to  corporate  responsibility  are
insufficient. We may face reputational damage in the event that our corporate responsibility procedures or standards do
not  meet  the  standards  set  by  various  constituencies.  Furthermore,  if  our  competitors’  corporate  responsibility
performance is perceived to be greater than ours, potential or current investors may elect to invest with our competitors
instead. In addition, in the event that we communicate or disclose certain initiatives and goals regarding environmental,
social and governance matters, we could fail, or be perceived to fail, in our achievement of such initiatives or goals, or we
could be criticized for the scope of such initiatives or goals or be subject to litigation for such failures. If we fail to satisfy
the  expectations  of  investors  and  other  stakeholders  or  our  initiatives  are  not  executed  as  planned,  our  reputation  and
financial results could be adversely affected.

Because we do not anticipate paying any cash dividends on our ordinary shares in the foreseeable future, capital
appreciation, if any, would be your sole source of gain.

Under Cayman Islands law, we may only make distributions by way of dividend out of profits, or out of our share
premium account (provided that immediately following the date that the dividend is proposed to be paid we are able to
pay our debts as they fall due in the ordinary course of business). We have never declared or paid any cash dividends on
our  ordinary  shares.  We  currently  anticipate  that  we  will  retain  future  earnings  for  the  development,  operation  and
expansion  of  our  business  and  do  not  anticipate  declaring  or  paying  any  cash  dividends  for  the  foreseeable  future.  In
addition, the Note Purchase Agreement prohibits us from paying dividends during its term and the terms of existing and
future financing agreements may also preclude us from paying dividends.  As a result, capital appreciation, if any, of our
ordinary shares would be your sole source of gain on an investment in our ordinary shares for the foreseeable future. See
the “Dividend Policy” section of this Form 10-K for the year ended December 31, 2022 for additional information.

Table of Contents

Overview

We are a vertically integrated, clinical stage gene therapy company with six programs in clinical development and 
a broad pipeline of preclinical and research programs. We have core capabilities in viral vector design and optimization and 
gene therapy manufacturing, as well as a potentially transformative gene regulation platform technology that allows 
precise, dose responsive control of gene expression by oral small molecules with dynamic range that can exceed 5000-fold. 
Led by an experienced management team, we have taken a portfolio approach by licensing, acquiring and developing 
technologies that give us depth across both product candidates and indications. Our initial focus is on three distinct areas of 
unmet medical need: ocular diseases, including both inherited retinal diseases as well as large degenerative ocular diseases, 
neurodegenerative diseases, and severe forms of xerostomia.  Though initially focusing on the eye, central nervous system 
and salivary gland, we intend to expand our focus in the future to develop additional gene therapy treatments for patients 
suffering from a range of serious diseases.

We are an exempted company incorporated under the laws of the Cayman Islands in 2018, and prior to that, we

commenced operations as MeiraGTx Limited, a private limited company incorporated under the laws of England and
Wales in 2015. Our discussion of our financial condition and results of operations is based upon our financial statements,
which have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”).
Since our formation, we have devoted substantially all of our resources to developing our technology platform, establishing
our viral vector manufacturing facilities and our cGMP plasmid and DNA production facility and developing
manufacturing processes, advancing the product candidates in our ophthalmology, salivary gland and neurodegenerative
disease programs, building our intellectual property portfolio, organizing and staffing our company, developing our
business plan, raising capital, and providing general and administrative support for these operations. To date, we have
financed our operations primarily with cash on hand and proceeds from the sales of our Series A ordinary shares,
Convertible Preferred C Shares and ordinary shares. Through December 31, 2022, we received gross proceeds of
approximately $471.0 million from sales of our ordinary shares, Series A ordinary shares and convertible preferred C
shares, gross proceeds of approximately $75.0 million from issuance of debt and $130.0 million from the collaboration,
option and license agreement with Janssen Pharmaceuticals, Inc. (“Janssen”), one of the Janssen Pharmaceuticals
Companies of Johnson & Johnson (the “Collaboration Agreement”). As of December 31, 2022, we had cash and cash
equivalents of $115.5 million, as well as $21.3 million we expect to receive from Janssen in the first quarter of 2023 in
connection with the Collaboration Agreement.

We are a clinical stage company and have not generated any product revenues to date. We have six clinical

programs and a pipeline of preclinical programs. Since inception, we have incurred significant operating losses. Our net
losses for the years ended December 31, 2022 and 2021 were $129.6 million and $79.6 million, respectively. As of
December 31, 2022, we had an accumulated deficit of $470.2 million. We do not expect to generate revenue from sales of
products for several years, if at all. Under the Collaboration Agreement, we received an upfront payment in the amount of
$100.0 million in March 2019 and a milestone payment in the amount of $30.0 million in December 2021. Additionally,
pursuant to the Collaboration Agreement, we are eligible to receive research and development funding and additional
potential milestone payments and royalties.

Our total operating expenses were $132.3 million and $110.5 million for the years ended December 31, 2022 and 

2021, respectively. While we expect our operating expenses to continue to increase in connection with our ongoing 
development activities related to our product candidates, including the ongoing Phase 3 Lumeos clinical trial of 
botaretigene sparoparvovec for the treatment of patients with XLRP, we believe that certain of these increases will be 
partially offset by the research funding in connection with the Collaboration Agreement.  In addition, we expect to continue 
incurring increasing costs associated with our clinical activities for AAV-hAQP1 for the treatment of radiation-induced 
xerostomia and xerostomia associated with Sjogren’s syndrome, as well as for AAV-GAD for the treatment of Parkinson’s 
disease. We also incurred expenses during the year ended December 31, 2022 and expect to continue to incur expenses 
related to research activities in additional therapeutic areas to expand our pipeline, developing our potentially 
transformative gene regulation technology, hiring additional personnel as needed in manufacturing, research, clinical 
operations, quality and other functional areas, and associated cash and share-based compensation expense, as 

109

Table of Contents

well as the further development of internal manufacturing capabilities and capacity and other associated costs including the 
management of our intellectual property portfolio.

On August 2, 2022 we, as borrower, and the Subsidiary Guarantors, entered into the Financing Agreement by and 

among the Company, the Subsidiary Guarantors, the lenders and other parties from time to time party thereto and 
Perceptive, as administrative agent and lender. On December 19, 2022, the Financing Agreement was converted to a Note 
Purchase Agreement between the same parties and under substantially the same terms and conditions as the Financing 
Agreement, subject to certain customary note constitution terms.  

The Note Purchase Agreement provides for the issuance of the Tranche 1 Notes in an initial amount of $75.0
million, and we may request the issuance of the Tranche 2 Notes in an additional amount of $25.0 million to be made
available at Perceptive’s sole discretion before August 2, 2024. The Note Purchase Agreement matures on August 2, 2026
and is interest-only during the term. We have the option to redeem outstanding principal notes at any time along with an
applicable early redemption fee. Outstanding amounts under the Note Purchase Agreement bear interest at a fluctuating
rate per annum equal to 10.00% plus the secured overnight financing rate administered by the Federal Reserve Bank of
New York for a one-month tenor, subject to a 1.00% floor.

On November 9, 2022, we entered into a securities purchase agreement with JJDC, pursuant to which we, in a

private placement, agreed to issue and sell to JJDC an aggregate of 3,742,514 ordinary shares at a purchase price of $6.68
per share for gross proceeds of approximately $25.0 million.

We will require additional capital in the future, which we may raise through equity offerings, debt financings,

marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements or other
sources to enable us to complete the development and potential commercialization of our product candidates. Furthermore,
we expect to continue incurring costs associated with being a public company. Adequate additional financing may not be
available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a negative effect
on our financial condition and our ability to pursue our business strategy. In addition, attempting to secure additional
financing may divert the time and attention of our management from day-to-day activities and harm our product candidate
development efforts. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay,
reduce or eliminate certain of our research and development programs.

Based on our cash and cash equivalents at December 31, 2022 and the research funding and milestone payments 

we expect to receive under the Collaboration Agreement, we estimate that such funds will be sufficient to enable us to fund 
our operating expenses and capital expenditure requirements through the fourth quarter of 2024.  We have based these 
estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we 
currently expect. See “Liquidity and Capital Resources.” Because of the numerous risks and uncertainties associated with 
the development of our product candidates, any future product candidates, our platform and technology and because the 
extent to which we may enter into collaborations with third parties for development of any of our product candidates is 
unknown, we are unable to estimate the amounts of increased capital outlays and operating expenses associated with 
completing the research and development of our product candidates. 

Adequate additional funds may not be available to us on acceptable terms, or at all. To the extent that we raise

additional capital through the sale of equity or convertible securities, your ownership interest will be diluted, and the terms
of these securities may include liquidation or other preferences that adversely affect your rights as a shareholder. Any
future debt financing or preferred equity or other financing, if available, may involve agreements that include covenants
limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or
declaring dividends and may require the issuance of warrants, which could potentially dilute your ownership interests.

If we raise additional funds through collaborations, strategic alliances, or licensing arrangements with third
parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or

product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds
through equity or debt financings when needed, we may be required to delay, limit, reduce, or terminate our product
development programs or any future commercialization efforts or grant rights to develop and market product candidates
that we would otherwise prefer to develop and market ourselves.

Because of the numerous risks and uncertainties associated with drug development, we are unable to predict the
timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are
able to generate revenue from product sales, we may not become profitable. If we fail to become profitable or are unable to
sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be
forced to reduce or terminate our operations.

Highlights and Recent Developments

Recent Development Highlights and Anticipated 2023 Milestones

Botaretigene Sparoparvovec for the Treatment of XLRP:  

● On October 1, 2022, clinical data from a Phase 1/2 MGT009 clinical trial (NCT03252847) were presented in a
late-breaking oral presentation at the Retina Subspecialty Day program of the AAO 2022 Annual Meeting;
treatment with botaretigene sparoparvovec was found to have an acceptable safety profile and efficacy
assessments in this study and demonstrated improvements in retinal sensitivity, visual function and functional
vision.1

● Further sensitivity analysis was conducted on study participants by applying the Phase 3 Lumeos

(NCT04671433) study eligibility criteria that corroborated the endpoints selected for the Phase 3 study.1

● We, in collaboration with Janssen, are dosing patients in the pivotal Phase 3 Lumeos clinical trial of botaretigene

sparoparvovec and remain on track for a BLA submission in 2024.

linked Retinitis Pigmentosa (XLRP). Abstract #30071754. Presented at the 2022 American Academy of Ophthalmology
Annual Meeting.

AAV-hAQP1 for the Treatment of Grade 2/3 Radiation-Induced Xerostomia:  

● We reported positive clinical data from the AQUAx Phase 1 clinical trial in December 2022.

o Clinically meaningful improvements in xerostomia symptoms and disease burden in two validated
Patient-Reported Outcome (PRO) measures in both unilateral and bilateral treated cohorts were
demonstrated.

◾ 18/24, or 75% achieved clinically meaningful symptom improvement using the Global Rate of

Change (GRCQ) PRO.

◾ Using the Xerostomia Questionnaire (XQ), 71% (17/24) reported an improvement of >8 points

(clinically meaningful), and 67% (16/24) had an improvement of ≥10 (considered
transformative by KOLs).

o Meaningful increases in whole saliva flow rates were observed post-treatment, providing objective

evidence of the biological activity of AAV-hAQP1 treatment.

o Early long-term follow-up data suggest durability of improvement 2+ years post-treatment.
o AAV-hAQP1 appears safe and well-tolerated at each dose tested.

● All participants are followed for 1 year post-treatment and then enter a long-term follow-up study for another 4

years.

● We intend to present the final 12 month data from the bilateral treated cohorts from the AQUAx Phase 1 study in

the second quarter of 2023.

● Based on the favorable safety and efficacy profile of AAV-hAQP1 in the AQUAx Phase 1 study, we intend to

initiate a randomized, double-blind, placebo-controlled, Phase 2 study evaluating the bilateral administration of
two active doses of AAV-hAQP1 in the second quarter of 2023.

AAV-GAD for the Treatment of Parkinson’s Disease:

● We are now dosing patients in the AAV-GAD clinical trial under a new IND using material manufactured in our

cGMP facility in London, United Kingdom using our proprietary production process.

● The AAV-GAD trial is a three-arm randomized Phase 1 clinical bridging study with subjects randomized to one of

two doses of AAV-GAD or sham control.

● The objective of the AAV-GAD trial (NCT05603312) is to evaluate the safety and tolerability of AAV-mediated
delivery of glutamic acid decarboxylase (GAD) gene transfer into the subthalamic nuclei (STN) of participants
with Parkinson's disease.

● Completion of enrollment is anticipated by the third quarter of 2023.

Riboswitch Gene Regulation Platform & Vector Engineering:

● We exhibited 15 poster presentations at the European Society of Gene and Cell Therapy 2022 Annual Congress,
which included data from our novel gene regulation platform, including the first data demonstrating the potential
to regulate cell therapies including CAR-T, as well as data from our promoter platforms and several new,
optimized pre-clinical programs addressing severe unmet needs for indications such as amyotrophic lateral
sclerosis (ALS) and Wilson’s disease. In addition, we made several presentations on our proprietary viral vector
manufacturing technology and potency assay development.

● Our next-generation riboswitch-based gene regulation platform can be used to precisely control the expression of

any gene delivered in any context with an unprecedented dynamic range using novel, synthetic, orally delivered
small molecules.

● We now have over 30 novel orally available small molecules with high specificity and potency to our riboswitch
aptamers moving through PK, biodistribution and toxicology studies, with the first GMP material for IND
currently being manufactured.

Gene Therapy Manufacturing:

● Our wholly-owned facilities have now produced GMP clinical trial material for 6 different indications, using
multiple AAV serotypes, including administration into the eye, salivary gland and central nervous system.

● We believe that our proprietary platform production process has produced one of the highest yields and full ratios

in the industry.

● We believe that bringing all aspects of testing and vector production in-house reduces regulatory risk, ensures the

highest quality of products, lowers costs and helps avoid bottlenecks in clinical development.

● In addition to our 30,000-square-foot facility in London, we now have a 150,000-square-foot plant in Shannon,

Ireland which contains three facilities: one built to be flexible and scalable for viral vector production, another to
manufacture plasmid DNA – the critical starting material for producing gene therapy products – and third, a
Quality Control (QC) hub performing advanced biochemical quality control testing appropriate for
commercialization.

Components of Our Results of Operations

License Revenue

Our license revenue consisted of the amortization of the upfront and milestone payments we received in

connection with the Collaboration Agreement.

Operating Expenses

Our operating expenses since inception have consisted primarily of general and administrative costs and research

and development costs.

112

Table of Contents

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including share-based
compensation, for personnel in our executive, finance, legal, business development and administrative functions. General
and administrative expenses also include legal fees relating to intellectual property and corporate matters; professional fees
for accounting, auditing, tax and consulting services; insurance costs; travel expenses; and office facility-related expenses,
which include direct depreciation costs.

We expect that our general and administrative expenses will increase in the future as we increase our personnel

headcount to support increased research and development activities. We have also incurred and expect to continue to incur
increased expenses associated with being a public company, including costs of accounting, audit, legal, regulatory and tax-
related services associated with maintaining compliance with Nasdaq and SEC requirements; director and officer insurance
costs; and investor and public relations costs.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our

discovery efforts, and the development of our product candidates, and include:

● employee-related expenses, including salaries, benefits and travel of our research and development

personnel;

● expenses incurred in connection with third-party vendors that conduct clinical and preclinical studies and

manufacture the drug product for the clinical trials and preclinical activities;

● acquisition of in process research and development;

● costs associated with clinical and preclinical activities including costs related to facilities, supplies, rent,

insurance, certain legal fees, share-based compensation, and depreciation; and

● expenses incurred with the development and operation of our manufacturing facilities.

We expense research and development costs as incurred.

Research and development activities are central to our business model. We expect that our research and
development expenses will continue to increase substantially for the foreseeable future as we initiate additional preclinical
and clinical trials of our existing product candidates, including the ongoing Phase 3 Lumeos trial of botaretigene
sparoparvovec for the treatment of patients with XLRP, and continue to discover and develop additional product
candidates. Certain of these increases in research and development costs will be partially offset by the research funding
provided in connection with the Collaboration Agreement we entered into in January 2019. In addition, we expect to
continue incurring increasing research and development costs associated with our clinical activities for AAV-hAQP1 for
the treatment of radiation-induced xerostomia and xerostomia associated with Sjogren’s syndrome, as well as for AAV-
GAD for the treatment of Parkinson’s disease.

We cannot determine with certainty the duration and costs of future clinical trials of our product candidates or any

other product candidate we may develop or if, when, or to what extent we will generate revenue from the
commercialization and sale of any product candidate for which we obtain marketing approval. We may never succeed in
obtaining marketing approval for any product candidate. The duration, costs and timing of clinical trials and development
of our existing product candidates or any other product candidate we may develop will depend on a variety of factors,
including:

113

Table of Contents

● the scope, rate of progress, expense and results of clinical trials of our existing product candidates, as well as
of any future clinical trials of other product candidates and other research and development activities that we
may conduct;

● uncertainties in clinical trial design and patient enrollment rates;

● the actual probability of success for our product candidates, including the safety and efficacy, early clinical

data, competition, manufacturing capability and commercial viability;

● significant and changing government regulation and regulatory guidance;

● the timing and receipt of any marketing approvals; and

● the expense of filing, prosecuting, defending and enforcing any patent claims and other intellectual property

rights.

A change in the outcome of any of these variables with respect to the development of a product candidate could

mean a significant change in the costs and timing associated with the development of that product candidate. For example,
if the FDA or another U.S. or foreign regulatory authority were to require us to conduct clinical trials beyond those that we
anticipate will be required for the completion of clinical development of a product candidate, or if we experience
significant delays in our clinical trials due to patient enrollment or other reasons, we would be required to expend
significant additional financial resources and time on the completion of clinical development.

Other non-operating income (expense)

Other non-operating income (expense) includes the following:

Foreign currency (loss) gain

Our consolidated financial statements are presented in U.S. dollars, which is our reporting currency. The financial

position and results of operations of our subsidiaries MeiraGTx UK II Limited, MeiraGTx Ireland DAC, MeiraGTx
Netherlands B.V., MeiraGTx B.V. and MeiraGTx Belgium are measured using the foreign subsidiaries’ local currency as
the functional currency. These entities’ cash accounts holding U.S. dollars and intercompany payables and receivables are
remeasured based upon the exchange rate at the date of remeasurement with the resulting gain or loss included in the
consolidated statement of operations and comprehensive loss.

Other comprehensive income

Other comprehensive income includes the following:

Foreign currency translation gain

Expenses of subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the

period. Assets and liabilities have been translated at the rates of exchange on the consolidated balance sheet date. The
resulting translation gain adjustments are recorded directly as a separate component of shareholders’ equity and as other
comprehensive loss on the consolidated statements of operations and comprehensive loss.

114

Table of Contents

Critical Accounting Policies and Use of Estimates

Management’s discussion and analysis of our financial condition and results of operations is based on our

consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these
consolidated financial statements requires us to make estimates and judgements that affect the reporting amounts of assets,
liabilities and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. On
an ongoing basis, we evaluate our estimates and judgements, including those related to license and collaboration revenue,
share-based compensation and accrued expenses. We base our estimates on historical experience, known trends and events
and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for
making judgements about the carrying value of assets and liabilities that are not readily apparent from our sources. Actual
results may differ from these estimates under different assumptions.

While our significant accounting policies are described in more detail in the notes to our financial statements

appearing in this Form 10-K, we believe that the following accounting policies are those most critical to the judgments and
estimates used in the preparation of our financial statements.

Collaboration Arrangements

We evaluate our collaborative arrangements pursuant to Accounting Standards Codification (“ASC”) 808,

Collaborative Arrangements (“ASC 808”) and ASC 606, Revenue from Contracts with Customers (“ASC 606”). We
consider the nature and contractual terms of collaborative arrangements and assess whether the arrangement involves a
joint operating activity pursuant to which we are an active participant and are exposed to significant risks and rewards with
respect to the arrangement. If we are an active participant and exposed to significant risks and rewards with respect to the
arrangement, we account for the arrangement as a collaboration under ASC 808. To date, we have entered into two separate
collaboration agreements, both of which are with Janssen, which were determined to be within the scope of ASC 808.

ASC 808 does not address recognition or measurement matters related to collaborative arrangements. Payments

between participants pursuant to a collaborative arrangement that are within the scope of other authoritative accounting
literature on income statement classification are accounted for using the relevant provisions of that literature. If the
payments are not within the scope of other authoritative accounting literature, the income statement classification for the
payments is based on an analogy to authoritative accounting literature or if there is no appropriate analogy, a reasonable,
rational and consistently applied accounting policy election. Payments received from a collaboration partner to which this
policy applies may include upfront payments in respect of a license of intellectual property, development and
commercialization-based milestones, and royalties.

Revenue Recognition

Arrangements with collaborators may include licenses to intellectual property, research and development services,
manufacturing services for clinical and commercial supply, and participation on joint steering committees. We evaluate the
promised goods or services to determine which promises, or group of promises, represent performance obligations. In
contemplation of whether a promised good or service meets the criteria required of a performance obligation, we consider
the stage of development of the underlying intellectual property, the capabilities and expertise of the customer relative to
the underlying intellectual property, and whether the promised goods or services are integral to or dependent on other
promises in the contract. When accounting for an arrangement that contains multiple performance obligations, we must
develop judgmental assumptions, which may include market conditions, reimbursement rates for personnel costs,
development timelines and probabilities of regulatory success to determine the stand-alone selling price for each
performance obligation identified in the contract.

115

Table of Contents

When we conclude that a contract should be accounted for as a combined performance obligation and recognized

over time, we must then determine the period over which revenue should be recognized and the method by which to
measure revenue. We generally recognize revenue using a cost-based input method.

The Collaboration Agreement is accounted for under ASC 808, however, as ASC 808 does not address
recognition or measurement matters such as determining the appropriate unit of accounting or when the recognition criteria
are met, we account for the consideration received from Janssen in accordance with ASC 606. In accordance with ASC
606, we recognize revenue when the customer or collaborator obtains control of promised goods or services, in an amount
that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue
recognition for arrangements that we determine are within the scope of ASC 606, we perform the following five steps:

i.

identify the contract(s) with a customer;

ii.

identify the performance obligations in the contract;

iii. determine the transaction price;

iv. allocate the transaction price to the performance obligations within the contract; and

v.

recognize revenue when (or as) the entity satisfies a performance obligation.

We only apply the five-step model to contracts when we determine that it is probable we will collect the

consideration we are entitled to in exchange for the goods or services we transfer to the customer.

At contract inception, once the contract is determined to be by analogy within the scope of ASC 606, we assess
the goods or services promised within the contract to determine whether each promised good or service is a performance
obligation. The promised goods or services for our arrangements typically consist of a license to our intellectual property
and research, development and manufacturing services. We may provide options to additional items in such arrangements,
which are accounted for as separate contracts when the customer elects to exercise such options, unless the option provides
a material right to the customer. Performance obligations are promises in a contract to transfer a distinct good or service to
the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is
separately identifiable from other promises in the contract. Goods or services that are not individually distinct performance
obligations are combined with other promised goods or services until such combined group of promises meet the
requirements of a performance obligation.

We determine transaction prices based on the amount of consideration we expect to receive for transferring the
promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. At contract
inception for arrangements that include variable consideration, we estimate the probability and extent of consideration we
expect to receive under the contract utilizing either the most likely amount method or expected amount method, whichever
best estimates the amount expected to be received. We then consider any constraints on the variable consideration and
include in the transaction price variable consideration to the extent it is deemed probable that a significant reversal in the
amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is
subsequently resolved.

We then allocate the transaction price to each performance obligation based on the relative standalone selling price

and recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation
when (or as) control is transferred to the customer and the performance obligation is satisfied. For performance obligations
which consist of licenses and other promises, we utilize judgment to assess the nature of the combined performance
obligation to determine whether the combined performance obligation is satisfied over time or at

116

Table of Contents

a point in time and, if over time, the appropriate method of measuring progress. We evaluate the measure of progress each
reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

We record amounts as accounts receivable when the right to consideration is deemed unconditional. When

consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or
services to the customer under the terms of a contract, a contract liability is recorded as deferred revenue.

Amounts received prior to satisfying the revenue recognition criteria are recognized as deferred revenue in our
consolidated balance sheet. Amounts expected to be recognized as revenue within the 12 months following the balance
sheet date are classified as deferred revenue – related party, current. Amounts not expected to be recognized as revenue
within the 12 months following the balance sheet date are classified as deferred revenue – related party.

Income Taxes

Since we have recurring losses and a valuation allowance against deferred tax assets, there was no tax expense 

(benefit) for the years ended December 31, 2022 and 2021.  

Research and Development

Research and development costs are charged to expense as incurred.  These costs include, but are not limited to, 

employee-related expenses, including salaries, benefits and travel of our research and development personnel; expenses 
incurred under agreements with contract research organizations and investigative sites that conduct clinical and preclinical 
studies and manufacture the drug product for the clinical studies and preclinical activities; acquisition of in-process 
research and development; facilities; supplies; rent, insurance, certain legal fees, stock-based compensation, depreciation 
and other costs associated with clinical and preclinical activities and regulatory operations.  Research funding under 
collaboration agreements and refundable research and development credits / tax credits received are recorded as an offset to 
these costs.

Costs for certain development activities, such as outside research programs funded by us, are recognized based on 
an evaluation of the progress to completion of specific tasks with respect to their actual costs incurred.  Payments for these 
activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and 
are reflected in the financial statements as prepaid or accrued research and development expense, as the case may be.

Share-Based Compensation

Options

We grant share options to employees, non-employee members of our board of directors and non-employee 

consultants as compensation for services performed.  Employee and non-employee members of the board of directors’ 
awards of share-based compensation are accounted for in accordance with ASC 718, Compensation—Stock Compensation, 
or ASC 718.  ASC 718 requires all share-based payments to employees and non-employee directors, including grants of 
share options, to be recognized in the statement of operations and comprehensive loss based on their grant date fair values.  
The grant date fair value of share options is estimated using the Black-Scholes option valuation model.

Using this model, fair value is calculated based on assumptions with respect to (i) the fair value of our ordinary

shares on the grant date; (ii) expected volatility of our ordinary share price, (iii) the periods of time over which employees
and members of our board of directors are expected to hold their options prior to exercise (expected term), (iv) expected
dividend yield on our ordinary shares, and (v) risk-free interest rates.

117

Table of Contents

Our ordinary shares were not traded on a public exchange prior to our IPO in June 2018.  Therefore, we believe 
that our future volatility will differ materially during the expected term from the volatility that would be calculated from 
our historical share prices to date.  Consequently, expected volatility is based on an analysis of guideline companies in 
accordance with ASC 718.  The expected dividend yield is zero as we have never paid dividends and do not currently 
anticipate paying any in the foreseeable future.  Risk-free interest rates are based on quoted U.S. Treasury rates for 
securities with maturities approximating the option’s expected term. 

Restricted Share Units

The Company grants restricted share units (“RSUs”) to employees, non-employee members of our board of

directors and non-employee consultants as compensation for services performed. Awards of RSUs are accounted for in
accordance with ASC 718, Compensation - Stock Compensation, or ASC 718. ASC 718 requires all share-based payments
to employees and non-employee directors, including grants of RSUs, to be recognized in the consolidated statement of
operations and comprehensive loss based on their grant date fair values. The grant date fair value of RSUs is determined
using the closing market price of the Company’s ordinary shares on the date of grant.

License revenue was $15.9 million for the year ended December 31, 2022, compared to $37.7 million for the year

ended December 31, 2021. This decrease is a result of the Company receiving a $30.0 million milestone payment in
connection with the Collaboration Agreement during the year ended December 31, 2021.

General and Administrative Expenses

General and administrative expenses were $46.6 million for the year ended December 31, 2022, compared to

$43.8 million for the year ended December 31, 2021.  The increase of $2.8 million was primarily due to an increase of $3.4 
million in share-based compensation, $2.0 million in legal and accounting fees, $1.3 million in consulting fees and $0.4 
million in depreciation. These increases were partially offset by a decrease of $1.7 million in payroll and payroll-

Gross research and development expenses for the year ended December 31, 2022 increased $24.7 million as

compared to the prior year primarily due to an increase of $8.9 million in costs related to the manufacturing of our clinical
trial materials, $6.5 million in payroll and payroll-related costs, $4.6 million in costs related to our pre-clinical research and
clinical trials, $4.5 million in share-based compensation, $2.7 million in rent and facility costs, $0.5 million in depreciation
and $1.1 million in other research costs. These increases were partially offset by a decrease of $2.6 million in license fees
and $1.5 million in acquired research and development costs.

Reimbursements under the Collaboration Agreement for the year ended December 31, 2022 increased $4.3

million as compared to the prior year primarily due to an increase in activity in the programs licensed under the
Collaboration Agreement.

Tax incentive reimbursement for the year ended December 31, 2022 increased $1.4 million as compared to the

prior year primarily due to the increase in allowable research and development costs.

Foreign Currency Loss

Foreign currency loss was $9.5 million for the year ended December 31, 2022 compared to a loss of $6.3 million
for the year ended December 31, 2021. The increase in the loss of $3.2 million was primarily due to an unrealized loss on
the valuation of the Company’s intercompany payables and receivables due to the strengthening of the U.S. dollar against
the pound sterling and euro during the year ended December 31, 2022.

Interest Income

Interest income was $0.8 million for the year ended December 31, 2022 compared to $0.2 million for the year

ended December 31, 2021. The increase was due to a higher interest rate during 2022.

Interest Expense

Interest expense was $4.9 million for the year ended December 31, 2022 compared to $0.3 million for the year 

ended December 31, 2021.  The increase was primarily due to the interest on the Financing Agreement entered into in 
August 2022, which was later converted to a Note Purchase Agreement in December 2022.

Other Comprehensive Income – Foreign Currency Translation Gain

Foreign currency translation adjustments resulted in a translation gain of $8.7 million for the year ended
December 31, 2022 compared to a translation gain of $2.2 million for the year ended December 31, 2021. The change in
the amount of $6.5 million was primarily due to a strengthening of the U.S. dollar against the pound sterling and euro
during the year ended December 31, 2022.

Liquidity and Capital Resources

Since our inception, we have incurred significant operating losses. For the year ended December 31, 2022, we

used $73.1 million in cash flows from operations. We did not generate positive cash flows from operations during the year
and there are no assurances that we will generate positive cash flows in the future. Additionally, there are no assurances
that we will be successful in obtaining an adequate level of financing for the development and commercialization of our
product candidates. We expect to incur significant expenses and operating losses for the foreseeable future as we advance
the preclinical and clinical development of our product candidates. We expect that our research and development and
general and administrative costs will increase in connection with conducting preclinical studies and clinical trials for our
product candidates, building out internal capacity to have products manufactured to support preclinical studies and clinical
trials, expanding our intellectual property portfolio, and providing general and administrative support for our operations. In
addition, on August 4, 2020 we entered into agreements to acquire the buildings for our second, large scale cGMP viral
vector manufacturing facility and our first cGMP plasmid and DNA production facility in Shannon, Ireland to expand our
manufacturing and supply chain capabilities. We closed on the acquisition of the first building in August 2020 and closed
on the second building in January 2021. As a result of these incurred and expected expenses we will need additional capital
to fund our operations, which we may obtain from additional equity or debt financings, collaborations, licensing
arrangements, or other sources.

We do not currently have any approved products and have never generated any revenue from product sales. We

have historically financed our operations primarily through cash on hand and proceeds from the sale of our ordinary shares,
series A ordinary shares and convertible preferred C shares. In March 2019 and December 2021, we received a
$100.0 million upfront payment and a $30.0 million milestone payment, respectively, in connection with the Collaboration
Agreement, which also provides us with research funding, and we are eligible to receive additional potential milestone
payments and royalties.

Additionally, on August 2, 2022, we, as borrower, and our Subsidiary Guarantors, entered into a Financing

Agreement by and among us, the Subsidiary Guarantors, the lenders and other parties from time to time party thereto and
Perceptive, as administrative agent and lender. On December 19, 2022, the Financing Agreement was converted to a Note
Purchase Agreement between the same parties and under substantially the same terms and conditions as the Financing
Agreement, subject to certain customary note constitution terms.

The Note Purchase Agreement provides for the issuance of the Tranche 1 Notes in an initial amount of $75.0
million, and we may request the issuance of the Tranche 2 Notes in an additional amount of $25.0 million to be made
available at Perceptive’s sole discretion before August 2, 2024. The Note Purchase Agreement matures on August 2, 2026
and is interest-only during the term. We have the option to redeem outstanding principal notes at any time along with an
applicable early redemption fee. Outstanding amounts under the Note Purchase Agreement bear interest at a fluctuating
rate per annum equal to 10.00% plus the secured overnight financing rate administered by the Federal Reserve Bank of
New York for a one-month tenor, subject to a 1.00% floor.

Our obligations under the Note Purchase Agreement are secured by our London, UK and Shannon, Ireland

manufacturing facilities, $3.0 million of our cash and the bank accounts of the Subsidiary Guarantors, and the issued and
outstanding equity interests of the Subsidiary Guarantors.

Table of Contents

The Note Purchase Agreement imposes covenants that include, among other things, enrolling in a Phase III trial

for AAV-RPGR on or before June 30, 2023, and ensuring the Company’s Shannon manufacturing facility meets or satisfies
all applicable good manufacturing practice requirements on or before December 31, 2023, as well as various restrictions on
us and the Subsidiary Guarantors, including restrictions pertaining to: (i) the incurrence of additional indebtedness, (ii)
limitations on liens, (iii) limitations on certain investments, (iv) making distributions, dividends and other payments, (v)
mergers, consolidations and acquisitions, (vi) dispositions of assets, (vii) our maintenance of at least $3 million in a U.S.
bank account, (viii) transactions with affiliates, (ix) changes to governing documents, (x) changes to certain agreements
and leases and (xi) changes in control; however, certain of these restrictions contain exceptions which allow us to license,
sell and monetize assets in our AAV-hAQP1 program in development to treat radiation-induced xerostomia, our AAV-GAD
program in development to treat Parkinson’s disease and our gene regulation platform technologies.

In connection with entering into the Financing Agreement, we granted warrants (the “Warrants”) to Perceptive to

purchase up to (i) 400,000 ordinary shares of the Company at an exercise price of $15.00 per share and (ii) 300,000
ordinary shares of the Company at an exercise price of $20.00 per share. The Warrants will expire on August 2, 2027.

Based on our current cash, cash equivalents and accounts receivable – related party at December 31, 2022 and the

research funding and milestone payments we expect to receive under the Collaboration Agreement, we estimate that we
will be able to fund our operating expenses and capital expenditure requirements through the fourth quarter of 2024. We
have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources
sooner than we expect.

Cash Flows

We had $115.5 million and $137.7 million of cash and cash equivalents as of December 31, 2022 and 2021,

respectively.

The following table summarizes our sources and uses of cash for the period presented:

During the year ended December 31, 2022, our cash used in operating activities of $73.1 million was primarily

due to our net loss of $129.6 million as we incurred expenses associated with research activities on our clinical programs,
manufacturing of our clinical trial materials, preclinical research programs and general and administrative expenses. The
net loss included non-cash charges of $46.9 million, which consisted of $28.6 million of share-based compensation, $9.5
million of a foreign currency loss, $8.7 million of depreciation and amortization, $0.4 million of a fair value downward
adjustment, $0.2 million of negative net change in right-of-use assets and liabilities, $0.2 million of amortization of interest
on asset retirement obligations and $0.4 million of amortization of the debt discount. Additionally, operating assets,
consisting of accounts receivable-related party, prepaid expenses, tax incentive receivable, other current assets and other
assets, decreased by $5.2 million and operating liabilities, consisting of accounts payable, accrued expenses, and deferred
revenue-related party, decreased by $4.4 million.

During the year ended December 31, 2021, our cash used in operating activities of $10.5 million was primarily
due to our net loss of $79.6 million as we incurred expenses associated with research activities on our clinical programs,
manufacturing of our clinical trial materials, preclinical research programs and general and administrative expenses. The
net loss included non-cash charges of $37.8 million, which consisted of $20.8 million of share-based compensation, $6.3
million of a foreign currency loss, $7.9 million of depreciation and amortization, $1.0 million of shares issued in
connection with a license agreement, $1.0 million of shares issued in connection with an asset acquisition, $0.4 million of a

other current assets and other assets, decreased by $17.3 million and operating liabilities, consisting of accounts payable,
accrued expenses, and deferred revenue-related party, increased by $14.0 million.

Investing Activities

Net cash used in investing activities for the year ended December 31, 2022 of $45.0 million consisted of

purchases of property and equipment for our manufacturing, laboratory and process development facilities and buildout
costs of our new facilities in Ireland.

Net cash used in investing activities for the year ended December 31, 2021 of $61.7 million consisted primarily of

$8.9 million in payments for the acquisition of the second building and long-term lease of our manufacturing facility in
Ireland, $6.5 million in connection with equity method and other investments and $46.3 million for purchases of property
and equipment for our manufacturing, laboratory and process development facilities and buildout costs of our new facilities
in Ireland.

Financing Activities

Net cash provided by financing activities was $95.2 million for the year ended December 31, 2022, which

consisted primarily of $75.0 million from issuance of the Tranche 1 Notes, $25.0 million from the issuance of ordinary
shares and $0.2 million in exercise of share options, which was offset by $2.8 million of payments for withholdings of
shares for income taxes, and financing fees of $2.2 million.

Net cash provided by financing activities was $1.7 million for the year ended December 31, 2021, which is

primarily from the exercise of share options.

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet arrangements under applicable SEC rules and do not have any

holdings in variable interest entities.

Emerging Growth Company Status

The Jumpstart Our Business Startups Act of 2012, (the “JOBS Act”), permits an “emerging growth company,”

which we are, to take advantage of an extended transition period to comply with new or revised accounting standards
applicable to public companies until those standards would otherwise apply to private companies. We have elected to take
advantage of this extended transition period through December 31, 2023.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are exposed to market risks in the ordinary course of our business.  These risks primarily include foreign 

currency exchange rate sensitivities and interest rate risk.

Foreign Currency Exchange Risk

We currently operate in the United States, the United Kingdom, the Netherlands, Ireland and Belgium.  Our 

activities in these jurisdictions expose us to currency exchange rate fluctuations primarily between the U.S. Dollar and the 
British pound sterling and euro.  When the U.S. Dollar strengthens against these currencies, the U.S. Dollar value of non-
U.S. Dollar based losses increases.  To the extent that our international activities recorded in local currencies increase in the 
future, our exposure to fluctuations in currency exchange rates will correspondingly increase. With respect to our foreign 
currency exposures as of December 31, 2022, we estimate a 10% unfavorable movement in foreign currency exchange
rates would have the effect of creating an additional foreign currency loss of approximately $28.1 million within other non-
operating income (expense) for the year ended December 31, 2022.

Interest Rate Risk

We are exposed to market risk as a result of changes in interest rates applicable to borrowings under our Note

Purchase Agreement. Borrowings under the Note Purchase Agreement bear interest at a fluctuating rate per annum equal to
10.00% plus the secured overnight financing rate (“SOFR”) administered by the Federal Reserve Bank of New York for a
one-month tenor, subject to a 1.00% floor. See Note 14 to our consolidated financial statements included elsewhere in this
Form 10-K. We may use interest rate cap derivatives, interest rate swaps or other interest rate hedging instruments to
economically hedge and manage interest rate risk with respect to our variable floating rate debt. As of December 31, 2022,
the annual interest rate was 13.02% and the outstanding balance of the Tranche 1 Notes was $75.0 million. Assuming no
change in the outstanding borrowings under the Note Purchase Agreement, we estimate that a hypothetical 1% increase in
the SOFR would increase our annual interest expense by approximately $0.8 million as of December 31, 2022.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of MeiraGTx Holdings plc and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of MeiraGTx Holdings plc and Subsidiaries (the
“Company”) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss,
shareholders' equity and cash flows for each of the two years in the period ended December 31, 2022, and the related notes
(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements
present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the
results of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity
with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion
on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement,
whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control
over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal
control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test
basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of
the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2016.

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Principal Business Activity

The Company

MeiraGTx Holdings plc and subsidiaries (the “Company” or “Meira Holdings”), an exempted company incorporated
under the laws of the Cayman Islands, is a vertically integrated, clinical stage gene therapy company with six
programs in clinical development and a broad pipeline of preclinical and research programs. The Company has core
capabilities in viral vector design and optimization and gene therapy manufacturing, as well as a potentially
transformative gene regulation platform technology that allows precise, dose responsive control of gene expression by
oral small molecules with dynamic range that can exceed 5000-fold. Led by an experienced management team, the
Company has taken a portfolio approach by licensing, acquiring and developing technologies that give depth across
both product candidates and indications. The Company’s initial focus is on three distinct areas of unmet medical need:
ocular diseases, including inherited retinal diseases as well as large degenerative ocular diseases, neurodegenerative
diseases and severe forms of xerostomia. Though initially focusing on the eye, central nervous system and salivary
gland, the Company intends to expand its focus in the future to develop additional gene therapy treatments for patients
suffering from a range of serious diseases. The Company also owns and operates a current good manufacturing
practices, or cGMP, multi-product, multi-viral vector manufacturing facility in London, United Kingdom (“UK”),
which includes fill and finish capabilities and can supply the Company’s clinical and potential commercial material.
Additionally, the Company expanded its manufacturing and supply chain capabilities by acquiring a second, large
scale cGMP viral vector manufacturing facility and its first cGMP plasmid and DNA production facility in Shannon,
Ireland. The Company completed the acquisition of these facilities in January 2021.

Acquisition

On October 4, 2021, the Company acquired Bullseye Therapeutics, Inc. (“Bullseye”), a company engaged in
developing mechanisms to deliver retinal drugs and gene therapies to the eye. Bullseye was renamed MeiraGTx
Therapeutics, Inc.

This acquisition is part of the Company’s continuing efforts to expand its focus to develop additional gene therapy
treatments for patients suffering from a range of serious diseases. (See Note 3 for additional information).

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles
generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is
meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting
Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards
Board (“FASB”).

Liquidity

The Company has not yet achieved profitable operations. There is no assurance that profitable operations, if ever
achieved, could be sustained on a continuing basis. In addition, development activities, clinical and preclinical testing,
and commercialization of the Company’s product candidates will require significant additional financing. The
Company’s accumulated deficit at December 31, 2022 totaled $470.2 million, and management expects to incur
substantial losses in future periods. The success of the Company is subject to certain risks and uncertainties, including
among others, uncertainty of product development; competition in the Company’s field of use; uncertainty of capital
availability; uncertainty in the Company’s ability to enter into agreements with collaborative partners; expanding and
protecting the Company’s intellectual property portfolio; dependence on third parties; dependence on key personnel;
the COVID-19 pandemic and mitigation measures. For the year ended December 31, 2022, the Company used $73.1
million in cash flows from operations and there are no assurances that the Company will

generate positive cash flows in the future. Additionally, there are no assurances that the Company will be successful in
obtaining an adequate level of financing for the development and commercialization of its product candidates.

As of December 31, 2022, the Company had cash and cash equivalents in the amount of $115.5 million, which
consisted of depository and money market accounts held at large international banks. On January 30, 2019, the
Company entered into a collaboration, option and license agreement with Janssen Pharmaceuticals, Inc. (“Janssen”),
one of the Janssen Pharmaceuticals Companies of Johnson & Johnson (the “Collaboration Agreement”), for the
research, development and commercialization of gene therapies for the treatment of inherited retinal diseases (“IRD”).
Under the terms of the Collaboration Agreement, the Company received an upfront payment of $100.0 million in
March 2019 and a $30.0 million milestone payment in December 2021. The Company also receives funding for certain
research, manufacturing, clinical development and commercialization costs, potential additional milestone payments
upon the achievement of such milestones and royalties on future net sales of products. The Company estimates that its
cash and cash equivalents on hand and accounts receivable – related party at December 31, 2022 will be sufficient to
cover its expenses for at least the next twelve months from the date of issuance of these consolidated financial
statements.

Risks and Uncertainties

The Company operates in an industry that is subject to intense competition, government regulation and rapid
technological change. The Company’s operations are subject to significant risk and uncertainties including financial,
operational, technological, regulatory and other risks, including the potential risk of business failure.

There are also many uncertainties regarding the pandemic caused by the novel coronavirus, or COVID-19, and the
Company continues to monitor the impact of the pandemic on all aspects of its business, including how the pandemic
will impact its financial condition, liquidity, operations, clinical studies, employees, vendors, and industry. While the
pandemic did not materially affect the Company's financial results and business operations in the year ended
December 31, 2022 and 2021, the Company is unable to predict the impact that COVID-19 will have on its financial
position and operating results in future periods due to numerous uncertainties. The Company will continue to assess
the evolving impact of the COVID-19 pandemic and will make adjustments to its operations as necessary.

The Company’s capital resources and operations to date have been funded primarily with the proceeds from the
Collaboration Agreement and private and public equity offerings, as well as the proceeds from the debt financing
described in Note 14. In the future, the Company may seek to raise additional capital through equity offerings, debt
financings, marketing and distribution arrangements and other collaborations, strategic alliances and licensing
arrangements or other sources to enable it to complete the development and potential commercialization of its product
candidates. The COVID-19 outbreak and mitigation measures also have had, and may continue to have, an adverse
impact on global economic conditions, which could have an adverse effect on the Company’s ability to raise capital
when needed.

Use of Estimates

Management considers many factors in selecting appropriate financial accounting policies and controls, and in
developing the estimates and assumptions that are used in the preparation of these consolidated financial statements.
Management must apply significant judgment in this process. In addition, other factors may affect estimates, including
expected business and operational changes, sensitivity and volatility associated with the assumptions used in
developing estimates, and whether historical trends are expected to be representative of future trends. The estimation
process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management
must select an amount that falls within that range of reasonable estimates. This process may result in actual results
differing materially from those estimated amounts used in the preparation of the financial statements if these results
differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such
assumptions are reasonable when made. In preparing these consolidated financial statements, management used
significant estimates in the following areas, among others: collaboration revenue, the accounting for research and
development costs, share-based compensation, leases, asset retirement obligations, fair value of financial instruments
and tax incentive receivable.

Additionally, the Company has made estimates of the impact of the COVID-19 pandemic within the consolidated
financial statements and there may be changes to those estimates in future periods. Actual results may differ from
these estimates.

Cash and Cash Equivalents

The Company considers all highly liquid instruments with an original maturity of 90 days or less at the time of 
purchase to be cash equivalents.  Cash and cash equivalents consist of checking and money market accounts held at 
large international banks that are readily convertible into cash.

Financial Instruments

The carrying value of accounts receivable-related party, tax incentive receivable, other current assets, and accounts
payable reported in the consolidated balance sheets equal or approximate fair value due to their short maturities.

Tax Incentive Receivable

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Meira UK II is eligible to participate in a UK research and development tax incentive programs under which it is
eligible to receive a cash refund from His Majesty’s Revenue & Customs (“HMRC”) for a percentage of the qualified
research and development costs expended by Meira UK II under the small and medium sized enterprises (“SME”)
program and the research and development expenditures credit (“RDEC”) program. The SME cash refund is available
to companies with less than 500 employees and annual aggregate revenue of less than 100.0 million euros or total
aggregate assets less than 86.0 million euros during the reimbursable period. The Company’s estimate of the amount of
cash refund it expects to receive related to the SME and RDEC programs is included in tax incentive receivable in the
accompanying consolidated balance sheets and such amounts are recorded as a reduction of research and development
expense in the statements of operations. During the years ended December 31, 2022 and 2021, the Company recorded
reductions to research and development expenses of $6.8 million and $5.4 million, respectively.  

In addition, the Company incurs Value Added Tax (“VAT”) on services provided by UK and EU vendors, which it is
entitled to reclaim. The Company’s estimate of the amount of cash refund it expects to receive related to VAT was $1.1
million and $1.9 million as of December 31, 2022 and 2021, respectively, which is included in other current assets in
the accompanying consolidated balance sheets.

Fair Value Measurements

Fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an
orderly transaction between market participants at the measurement date and in the principal or most advantageous
market for that asset or liability. The fair value should be calculated based on assumptions that market participants
would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of
liabilities should include consideration of non-performance risk including the Company’s own credit risk.

The Company follows ASC Topic 820, Fair Value Measurements and Disclosures, or ASC 820, for application to
financial assets and liabilities. In addition to defining fair value, the standard expands the disclosure requirements
around fair value and establishes a fair value hierarchy for valuation inputs. The hierarchy prioritizes the inputs into
three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair
value measurement is reported in one of the three levels which are determined by the lowest level input that is
significant to the fair value measurement in its entirety. These levels are:

● Level 1: Observable inputs such as quoted prices in active markets for identical assets the reporting entity

has the ability to access as of the measurement date;

● Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or

indirectly; and

● Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity

to develop its own assumptions.

Equity Method and Other Investments

The Company accounts for equity investments under the equity method of accounting when the requirements for
consolidation are not met, and the Company has significant influence over the operations of the investee. Equity
method investments are initially recorded at cost and subsequently adjusted for the Company’s share of net income or
loss and cash contributions and distributions and are included in equity method and other investments in the
accompanying consolidated balance sheets. Equity investments that do not result in consolidation and are not
accounted for under the equity method are measured at fair value, with any changes in fair value recognized in net
income (loss). For any such investments that do not have readily determinable fair values, the Company elects the
measurement alternative to measure the investments at cost minus impairment, if any, plus or minus changes resulting
from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.
Equity method investments are reviewed for impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. If it is determined that a loss in value of the equity method investment is
other than temporary, an impairment loss is measured based on the excess of the carrying amount of an investment
over its estimated fair value. Impairment analyses are based on current plans, intended holding periods, and available
information at the time the analysis is prepared.

Concentrations of Credit Risk

The Company maintains its cash and cash equivalents primarily in depository and money market accounts within two
large financial institutions in the United States and one large financial institution in the United Kingdom and Ireland.
 Cash balances deposited at these major financial banking institutions exceed the insured limit. The Company has not
experienced any losses on its bank deposits and believes these deposits do not expose the Company to any significant
credit risk.

Intangible Assets

Intangible assets consist of purchased rights to licensed technology as it relates to the Company’s manufacturing 
processes and has future alternative use in the Company’s operations.  The licensed technology is being amortized on a 
straight-line basis over 7 years, which represents the estimated periods of benefit and the expected pattern of
consumption (see Note 7).

F-11

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the
straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are depreciated
over the lesser of their useful lives or the term of the lease (see Note 6).

The estimated useful lives of the asset categories are as follows:

Asset Category
Computer and office equipment
Laboratory equipment
Manufacturing equipment
Furniture and fixtures
Leasehold improvements

Useful Lives

3 years
5 years
7 years
5 years
lesser of useful life or
remaining term of lease

Expenditures for leasehold improvements are capitalized, and expenditures for maintenance and repairs are expensed
to operations as incurred.

ASC Topic 360, Property, Plant and Equipment, addresses the financial accounting and reporting for impairment or
disposal of long-lived assets. The Company reviews the recorded values of long-lived assets for impairment whenever
events or changes in business circumstances indicate that the carrying amount of an asset or group of assets may not be
fully recoverable. The Company did not record any material impairment charges in 2022 or 2021.

Leases

The Company accounts for leases in accordance with ASC 842. The Company determines if an arrangement is a lease
at contract inception. A lease exists when a contract conveys the right to control the use of identified property, plant, or
equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions:
(1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment),
and (2) the Company has the right to control the use of the identified asset. The Company accounts for the lease and
non-lease components as a single lease component.

From time to time the Company enters into direct financing lease arrangements that include a lessee obligation to
purchase the leased asset at the end of the lease term, a bargain purchase option, or provides for minimum lease
payments with a present value of 90% or more of the fair value of the leased asset at the date of lease inception.

Operating leases where the Company is the lessee are included in right-of-use (“ROU”) assets – operating leases and
lease obligations are included on the Company’s consolidated balance sheets. The lease obligations are initially and
subsequently measured at the present value of the unpaid lease payments at the lease commencement date and
subsequent reporting periods.

Finance leases where the Company is the lessee are included in ROU assets – finance leases, net and lease obligations
on the Company’s consolidated balance sheets. The lease obligations are initially measured in the same manner as for
operating leases and are subsequently measured at amortized cost using the effective interest method.

Key estimates and judgments include how the Company determined (1) the discount rate used to discount the unpaid
lease payments to present value, (2) lease term and (3) lease payments.

ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that
rate cannot be readily determined, its incremental borrowing rate. As most of the Company’s leases where it is the

F-12

    
 
 
 
 
 
Table of Contents

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

lessee do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information
available at commencement date in determining the present value of lease payments. The Company’s incremental
borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount
equal to the lease payments under similar terms. The Company uses the implicit rate when readily determinable.

The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional
periods covered by either a lessee option to extend (or not to terminate) the lease that is reasonably certain to be
exercised, or an option to extend (or not to terminate) the lease controlled by the lessor.

The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease
payments made at or before the lease commencement date less any lease incentives received.

For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the
lease liability, minus any accrued lease payments, less the unamortized balance of lease incentives received. Lease
expense for lease payments is recognized on a straight-line basis over the lease term.

For finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease
commencement date to the earlier of the end of its useful life or the end of the lease term unless the lease transfers
ownership of the underlying asset, or the Company is reasonably certain to exercise an option to purchase the
underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization
of the ROU asset is recognized and presented separately from interest expense on the lease liability.

The Company has elected not to recognize ROU assets and lease liabilities for all short-term leases that have a lease
term of 12 months or less at lease commencement. Lease payments associated with short-term leases are recognized as
an expense on a straight-line basis over the lease term.

Asset Retirement Obligations

Accounting for asset retirement obligations requires legal obligations associated with the retirement of long-lived 
assets to be recognized at fair value when incurred and capitalized as part of the related long-lived asset.  In the 
absence of quoted market prices, the Company estimates the fair value of its asset retirement obligations using Level 3 
present value techniques, in which estimates of future cash flows associated with retirement activities are discounted 
using a credit-adjusted risk-free rate.  Asset retirement obligations currently reported on the Company’s consolidated 
balance sheets were measured during a period of historically low interest rates.  The impact on measurements of new 
asset retirement obligations using different rates in the future may be significant.

The Company uses estimates to determine the asset retirement obligations at the end of the lease term and discounts
such asset retirement obligations using an estimated discount rate. Interest on the discounted asset retirement
obligation is amortized over the term of the lease using the effective interest method and is recorded as interest
expense in the consolidated statements of operations and comprehensive loss.

Share-Based Compensation Expense

Options

The Company grants share options to employees, non-employee members of the Company’s board of directors and
non-employee consultants as compensation for services performed. Employee and non-employee members of the
board of directors’ awards of share-based compensation are accounted for in accordance with ASC 718, Compensation
– Stock Compensation, or ASC 718. ASC 718 requires all share-based payments to employees and non-employee
directors, including grants of share options, to be recognized in the consolidated statement of operations and
comprehensive loss based on their grant date fair values. The grant date fair value of share options is estimated using
the Black-Scholes option valuation model.

Using this model, fair value is calculated based on assumptions with respect to (i) the fair value of the Company’s
ordinary shares on the grant date; (ii) expected volatility of the Company’s ordinary share price, (iii) the periods of
time over which the optionees are expected to hold their options prior to exercise (expected term), (iv) expected
dividend yield on the Company’s ordinary shares, and (v) risk-free interest rates.

The assumptions underlying these valuations represented management’s best estimate, which involved inherent
uncertainties and the application of management’s judgment. As a result, if the Company had used different
assumptions or estimates, the fair value of its ordinary shares and its share-based compensation expense could have
been materially different.

The fair value of ordinary shares after the Company’s IPO was determined based upon the closing share price on the
date of grant.

Since the Company’s ordinary shares had not been traded on a public exchange prior to the Company’s IPO and have
only been traded on a public exchange for a short period of time since the Company’s IPO, the Company believes that
it does not have sufficient company-specific information available to determine the expected term based on its
historical data. As a result, the expected term of share options granted to the optionees is determined using the average
of the vesting period and contractual life of the option, an accepted method for the Company’s option grants under the
Securities and Exchange Commission’s (“SEC”) Staff Accounting Bulletin No. 107 and No. 110, Share-Based
Payment.

Similarly, the Company believes that its future volatility could differ materially during the expected term from the
volatility that would be calculated from its historical share prices to date. Consequently, expected volatility is based on
an analysis of guideline companies and the Company’s own volatility in accordance with ASC 718. The expected
dividend yield is zero as the Company has never paid dividends and does not currently anticipate paying any in the
foreseeable future. Risk-free interest rates are based on quoted U.S. Treasury rates for securities with maturities
approximating the option’s expected term.

Restricted Share Units

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company grants restricted share units (“RSUs”) to employees, non-employee members of the Company’s board
of directors and non-employee consultants as compensation for services performed. Awards of RSUs are accounted for
in accordance with ASC 718, Compensation – Stock Compensation, or ASC 718. ASC 718 requires all share-based
payments to employees, non-employee members of the Company’s board of directors and non-employee consultants,
including grants of RSUs, to be recognized in the consolidated statement of operations and comprehensive loss based
on their grant date fair values. The grant date fair value of RSUs is determined using the closing market price of the
Company’s ordinary shares on the date of grant.

Collaboration Arrangements

The Company evaluates its collaborative arrangements pursuant to ASC 808, Collaborative Arrangements (“ASC
808”) and ASC 606, Revenue from Contracts with Customers (“ASC 606”). The Company considers the nature and
contractual terms of collaborative arrangements and assesses whether the arrangement involves a joint operating
activity pursuant to which the Company is an active participant and is exposed to significant risks and rewards with
respect to the arrangement. If the Company is an active participant and is exposed to significant risks and rewards with
respect to the arrangement, the Company accounts for the arrangement as a collaboration under ASC 808. To date, the
Company has entered into two separate collaboration agreements, both of which are with Janssen, which were
determined to be within the scope of ASC 808.

ASC 808 does not address recognition or measurement matters related to collaborative arrangements. Payments
between participants pursuant to a collaborative arrangement that are within the scope of other authoritative
accounting literature on income statement classification are accounted for using the relevant provisions of that
literature. If the payments are not within the scope of other authoritative accounting literature, the income statement
classification for the payments is based on an analogy to authoritative accounting literature or if there is no appropriate
analogy, a reasonable, rational and consistently applied accounting policy election. Payments received from a
collaboration partner to which this policy applies may include upfront payments in respect of a license of intellectual
property, development and commercialization-based milestones, and royalties.

Refer to the discussion in Note 12 for further information related to the accounting for the Collaboration Agreement.

Revenue Recognition

Arrangements with collaborators may include licenses to intellectual property, research and development services,
manufacturing services for clinical and commercial supply, and participation on joint steering committees. The
Company evaluates the promised goods or services to determine which promises, or group of promises, represent
performance obligations. In contemplation of whether a promised good or service meets the criteria required of a
performance obligation, the Company considers the stage of development of the underlying intellectual property, the
capabilities and expertise of the customer relative to the underlying intellectual property, and whether the promised
goods or services are integral to or dependent on other promises in the contract. When accounting for an arrangement
that contains multiple performance obligations, the Company must develop judgmental assumptions, which may
include market conditions, reimbursement rates for personnel costs, development timelines and probabilities of
regulatory success to determine the stand-alone selling price for each performance obligation identified in the contract.

When the Company concludes that a contract should be accounted for as a combined performance obligation and
recognized over time, the Company must then determine the period over which revenue should be recognized and the
method by which to measure revenue. The Company generally recognizes revenue using a cost-based input method.

F-15

Table of Contents

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Collaboration Agreement with Janssen is accounted for under ASC 808, however, as ASC 808 does not address
recognition or measurement matters such as determining the appropriate unit of accounting or when the recognition
criteria are met, the Company accounts for the consideration received from Janssen in accordance with ASC 606. In
accordance with ASC 606, the Company recognizes revenue when its customer or collaborator obtains control of
promised goods or services, in an amount that reflects the consideration which the Company expects to receive in
exchange for those goods or services. To determine revenue recognition for arrangements that the Company
determines are within the scope of ASC 606, it performs the following five steps:

i.

ii.

identify the contract(s) with a customer;

identify the performance obligations in the contract;

iii.

determine the transaction price;

iv.

v.

allocate the transaction price to the performance obligations within the contract; and

recognize revenue when (or as) the entity satisfies a performance obligation.

The Company only applies the five-step model to contracts when it determines that it is probable it will collect the
consideration it is entitled to in exchange for the goods or services it transfers to the customer.

At contract inception, once the contract is determined to be by analogy within the scope of ASC 606, the Company
assesses the goods or services promised within the contract to determine whether each promised good or service is a
performance obligation. The promised goods or services in the Company’s arrangements typically consist of a license
to the Company’s intellectual property and research, development and manufacturing services. The Company may
provide options to additional items in such arrangements, which are accounted for as separate contracts when the
customer elects to exercise such options, unless the option provides a material right to the customer. Performance
obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can
benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other
promises in the contract. Goods or services that are not individually distinct performance obligations are combined
with other promised goods or services until such combined group of promises meet the requirements of a performance
obligation.

The Company determines transaction price based on the amount of consideration the Company expects to receive for
transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of
both. At contract inception for arrangements that include variable consideration, the Company estimates the
probability and extent of consideration it expects to receive under the contract utilizing either the most likely amount
method or expected amount method, whichever best estimates the amount expected to be received. The Company then
considers any constraints on the variable consideration and includes in the transaction price variable consideration to
the extent it is deemed probable that a significant reversal in the amount of cumulative revenue recognized will not
occur when the uncertainty associated with the variable consideration is subsequently resolved.

The Company then allocates the transaction price to each performance obligation based on the relative standalone
selling price and recognizes as revenue the amount of the transaction price that is allocated to the respective
performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied.
For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the
nature of the combined performance obligation to determine whether the combined performance obligation is satisfied
over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company
evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and
related revenue recognition.

F-16

Table of Contents

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company records amounts as accounts receivable when the right to consideration is deemed unconditional. When
consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or
services to the customer under the terms of a contract, a contract liability is recorded as deferred revenue.

Amounts received prior to satisfying the revenue recognition criteria are recognized as deferred revenue in the
Company’s consolidated balance sheet. Amounts expected to be recognized as revenue within the 12 months following
the balance sheet date are classified as deferred revenue – related party, current. Amounts not expected to be
recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue –
related party.

The Company’s collaboration revenue arrangements include the following:

Up-front License Fees: If a license is determined to be distinct from the other performance obligations identified in the
arrangement, the Company recognizes revenues from nonrefundable, up-front fees allocated to the license when the
license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are
bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance
obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if
over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable,
up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the
measure of performance and related revenue recognition.

Milestone Payments: At the inception of an agreement that includes research and development milestone payments,
the Company evaluates each milestone to determine when and how much of the milestone to include in the transaction
price. The Company first estimates the amount of the milestone payment that the Company could receive using either
the expected value or the most likely amount approach. The Company primarily uses the most likely amount approach
as that approach is generally most predictive for milestone payments with a binary outcome. Then, the Company
considers whether any portion of that estimated amount is subject to the variable consideration constraint (that is,
whether it is probable that a significant reversal of cumulative revenue would not occur upon resolution of the
uncertainty.) The Company updates the estimate of variable consideration included in the transaction price at each
reporting date which includes updating the assessment of the likely amount of consideration and the application of the
constraint to reflect current facts and circumstances.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales,
and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize
revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of
the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any
revenue related to sales-based royalties or milestone payments based on the level of sales.

Research and Development Services: The Company is incurring research and development costs, with Janssen
responsible for up to 100% of the costs, depending on the type of research and development services being performed.
The Company records costs associated with the development activities as research and development expenses in the
consolidated statement of operations and comprehensive loss consistent with ASC 730, Research and Development.
The reimbursement of the research and development costs by Janssen is representative of the joint risk sharing nature
of the arrangement. The Company considered the guidance in ASC 808 and recognizes the payments received from
Janssen as a reduction to research and development expense when the related costs are incurred.

Research and Development

Research and development costs are charged to expense as incurred. These costs include, but are not limited to,
employee-related expenses, including salaries, benefits and travel of the Company’s research and development

Costs for certain development activities, such as Company funded outside research programs, are recognized based on
an evaluation of the progress to completion of specific tasks with respect to their actual costs incurred. Payments for
these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs
incurred, and are reflected in the consolidated financial statements as prepaid or accrued research and development
expenses, as the case may be.

Foreign Currencies

The Company’s consolidated financial statements are presented in U.S. dollars, the reporting currency of the 
Company. The financial position and results of operations of Meira UK II, Meira Ireland, Meira Netherlands, Meira 
Belgium and Meira B.V. are measured using the foreign subsidiaries’ local currency as the functional currency. These 
entities’ cash accounts holding U.S. dollars are remeasured based upon the exchange rate at the date of remeasurement 
with the resulting gain or loss included in the consolidated statements of operations and comprehensive loss.  Expenses 
of such subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. 
Assets and liabilities have been translated at the rates of exchange on the consolidated balance sheet dates. The 
resulting translation gain and loss adjustments are recorded directly as a separate component of shareholders' equity 
and as other comprehensive loss on the consolidated statements of operations and comprehensive loss.

Income Taxes

Income taxes are recorded in accordance with ASC Topic 740, Income Taxes, or ASC 740, which provides for deferred
taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected
future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets
and liabilities are determined based on the difference between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Realization of
net deferred tax assets is dependent on future taxable income. Valuation allowances are provided if, based upon the
weight of available evidence, it is more likely than not that some, or all, of the deferred tax assets will not be realized.
Realization of net deferred tax assets is dependent on future taxable income (see Note 11).

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax
positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely
than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based
upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of
December 31, 2022 and 2021, the Company recorded unrecognized tax positions of $0.9 and $0.7 million, 
respectively.  No interest and penalties have been accrued relative to the unrecognized tax positions.

The Company is required to estimate income taxes in each of the jurisdictions in which it operates.

Net Loss per Ordinary Share

Basic net loss per ordinary share is computed by dividing net loss by the weighted average number of shares of the
Company’s ordinary shares outstanding during the period of computation. Diluted net loss per ordinary share is

F-18

Table of Contents

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

computed similar to basic net loss per share except that the denominator is increased to include the number of
additional ordinary shares that would have been outstanding if the ordinary share equivalents had been issued at the
beginning of the year and if the additional ordinary shares were dilutive (treasury stock method) or the two-class
method, whichever is more dilutive. For all periods presented, basic and diluted net loss per ordinary share are the
same as any additional ordinary share equivalents would be anti-dilutive.

The following securities are considered to be ordinary share equivalents, but were not included in the computation of
diluted net loss per ordinary share because to do so would have been anti-dilutive:

Share options
Restricted share units
Warrants
Restricted ordinary shares subject to forfeiture

Recent Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of
Credit Losses on Financial Instruments, which adds a new Topic 326 to the Codification and removes the thresholds
that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans,
receivables, and held-to-maturity debt securities. Under current GAAP, companies generally recognize credit losses
when it is probable that the loss has been incurred. The revised guidance will remove all recognition thresholds and
will require companies to recognize an allowance for credit losses for the difference between the amortized cost basis
of a financial instrument and the amount of amortized cost that the company expects to collect over the instrument’s
contractual life. ASU 2016-13 also amends the credit loss measurement guidance for available-for-sale debt securities
and beneficial interests in securitized financial assets. The guidance is applicable for fiscal years beginning after
December 15, 2019 and interim periods within those years, however, the FASB extended the

effective date for smaller reporting companies to fiscal years beginning after December 15, 2022. The Company does
not believe that the adoption of this standard will have a significant impact on its related disclosures.

3.    Acquisition

Bullseye Therapeutics, Inc.

On October 4, 2021 (the “Bullseye Closing Date”), the Company acquired the stock of Bullseye, a company engaged
in developing mechanisms to deliver retinal drugs and gene therapies to the eye. As a result, Bullseye is a wholly-
owned subsidiary of the Company and was renamed MeiraGTx Therapeutics, Inc.

In connection with the acquisition of Bullseye, the consideration to Bullseye’s selling stockholders consisted of an
aggregate of 80,276 of the Company’s ordinary shares of which (i) 12,040 ordinary shares were issued on the Bullseye
Closing Date, (ii) 28,097 restricted ordinary shares were issued on the Bullseye Closing Date, with 50% of such
restricted ordinary shares scheduled to vest on each of the first and second anniversaries of the Bullseye Closing Date,
and (iii) 40,139 ordinary shares will be issued 18 months following the Bullseye Closing Date, provided that the shares
described in clauses (ii) and (iii) are subject to certain indemnification claims under the Bullseye Merger
Agreement. The Company also assumed $0.5 million of Bullseye’s liabilities (“Assumed Liabilities”). Total
consideration of $1.5 million was based on the closing price of the Company’s ordinary shares of $13.31 per share on
October 1, 2021, plus the Assumed Liabilities.

The Company determined this transaction represented an asset acquisition as substantially all of the value was in the
intellectual property as defined by ASC 805, Business Combinations (“ASC 805”). The asset acquisition of in-process
research and development was recorded at a fair value of $1.5 million as of October 4, 2021. The acquired in process
research and development was immediately charged to research and development expense in the consolidated
statement of operations and comprehensive loss as of the acquisition date since the Company determined that there
was no alternative future use for these assets.

The 40,139 ordinary shares that are to be issued 18 months following the Bullseye Closing Date were recorded as a
liability at a fair value of $0.5 million on the Bullseye Closing Date.  At December 31, 2022 and 2021, the liability 
was revalued to $0.3 million and $1.0 million, respectively, based upon the closing price of the Company’s ordinary
shares of $6.52 and $23.74 per share on December 31, 2022 and 2021, respectively.  The $0.7 million and $0.5 million
change in fair value was recorded as a fair value adjustment for the years ended December 31, 2022 and 2021,
respectively. The change in fair value was included as part of research and development expenses in the prior year, but
for comparative purposes it has been presented as a fair value adjustment in the consolidated statements of operations
and comprehensive loss.

Visiogene LLC

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

On January 4, 2021, the Company and Visiogene LLC (“Visiogene”) entered into a License and Investment Agreement
(“Visiogene License Agreement”) for an exclusive, worldwide license to certain of Visiogene’s intellectual property
relating to ocular gene therapy. Concurrently, the Company and Visiogene entered into a Preferred Unit Purchase
Agreement (“Visiogene Unit Agreement”) pursuant to which the Company purchased 3,000,000 Visiogene preferred
units. In connection with the two Visiogene agreements, the Company paid $5.0 million in cash and issued to
Visiogene 75,000 ordinary shares of the Company with a fair market value of $1.2 million based on the closing price
of the Company’s ordinary shares on the date of closing.

The Company accounted for the payments under the Visiogene License Agreement and Visiogene Unit Agreement as a
basket transaction and allocated $1.0 million to the Visiogene License Agreement and the remaining $5.2 million was
allocated to the Visiogene preferred units. The $1.0 million allocated to the Visiogene License Agreement was
expensed as acquired in-process research and development as the Company determined there was no alternative future
use. The Company accounts for this investment using the equity method of accounting.

During the years ended December 31, 2022 and 2021, the Company recorded de minimis research and development
expenses related to the Company’s share of Visiogene’s losses.

Other Equity Investment

During the year ended December 31, 2022, the Company recognized a $0.3 million impairment due to the dilution of 
the Company’s ownership percentage of the investment.  The $0.3 million impairment was recorded as a fair value
adjustment for the year ended December 31, 2022.

The Company’s 2018 Incentive Award Plan and 2016 Equity Incentive Plan (collectively, the “Plans”), were adopted
by the Company’s board of directors and shareholders. Under the Plans, the Company has granted share options and
restricted share units (“RSUs”) to selected officers, employees, non-employee members of the Company’s board of
directors and non-employee consultants. The Company’s board of directors or a committee thereof administers the
Plans. Upon the adoption of the 2018 Incentive Award Plan, the Company ceased issuing awards under the 2016
Equity Incentive Plan. The number of shares available for issuance under the 2018 Incentive Award Plan are increased
on January 1 of each calendar year beginning in 2019 and ending in and including 2028, by an amount equal to the
lesser of (A) 4% of the ordinary shares outstanding on the final day of the immediately preceding calendar year and
(B) a smaller number of shares determined by the Company's board of directors. Under the 2018 Incentive Award Plan
the Company initially reserved up to 3,054,996 shares for issuance, which has been increased to 9,171,660 as of
December 31, 2022. As of December 31, 2022, 843,802 shares remain available for future issuance. In January 2023,
the number of shares available for issuance under the 2018 Incentive Award Plan increased by 1,939,088 shares. Also,
in February 2023, the Company’s board of directors approved up to 2,250,000 options and restricted share units to be
granted to certain executives, employees and consultants, in each case, under the 2018 Incentive Award Plan.

ASC 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of available
evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. After
consideration of all the evidence, both positive and negative, the Company has recorded a full valuation allowance,
after consideration of the reversal of the deferred tax liabilities for the ROU assets and fixed assets, against its deferred
tax assets at December 31, 2022 and 2021 because the Company's management has determined that is it more likely
than not that these assets will not be fully realized.

Changes to the UK corporation tax rates have been announced which will impact future accounting periods. Finance
Act 2021 increases the UK corporation tax rate from 19% to 25% effective April 1, 2023 for companies with profits in
excess of GBP 250,000. As the Company does not expect to be able to utilize its carryforward tax losses in the UK
until after April 2023, the deferred tax has been calculated using a tax rate of 25%.

As of December 31, 2022 and 2021, the Company recorded unrecognized tax positions of $0.9 million and $0.7
million, respectively. The unrecognized tax positions are netted with deferred tax assets above with full valuation
allowance. The changes to unrecognized tax positions for 2022 and 2021 were as follows (in thousands):

no amounts have been recognized in the Company's statements of operations and comprehensive loss.

The Company files income tax returns in the United States, UK, various foreign jurisdictions and various U.S. state 
jurisdictions.  In the U.S., all years remain subject to examination.  The earliest year subject to examination in the UK 
is 2020.

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

MeiraGTx Holdings plc is a UK tax resident with no earnings in its foreign subsidiaries and the Company does not 
expect any temporary basis difference in its investment in these subsidiaries to reverse in the foreseeable future.  
Therefore, the Company has not recorded deferred taxes on the outside basis difference in its foreign subsidiaries.  It is 
not probable to compute the amounts, if any.

12.  Related Party Transactions

Collaboration and License Agreements

Janssen Pharmaceuticals, Inc.

On January 30, 2019, the Company entered into a Collaboration Agreement with Janssen for the research,
development and commercialization of gene therapies for the treatment of IRD. Under the agreement, Janssen paid the
Company a non-refundable upfront fee of $100.0 million. Janssen and the Company will collaborate to develop the
Company’s current clinical programs in retinitis pigmentosa and two genetic forms of achromatopsia and Janssen has
the exclusive right to commercialize these three product candidates (“Clinical IRD Product Candidates”) globally.

Pursuant to the Collaboration Agreement, the Company and Janssen also agreed on a research collaboration to develop
a pipeline of preclinical inherited retinal disease gene therapy candidates (“Research IRD Product Candidates”). The
parties will select and prioritize the Research IRD Product Candidates and Janssen has the right to opt-in for a fee for
each of the specified targets (each an “Option Target”) to obtain certain development, manufacturing and
commercialization rights for the Research IRD Product Candidates.

Unless terminated earlier under certain termination clauses, the Collaboration Agreement will continue in effect, on a
product-by-product and country-by-country basis, until such time as the royalty terms expire in such country. The
Company has determined enforceable rights exist in the Collaboration Agreement as the termination clauses are
substantive termination penalties by way of the non-refundable upfront fee and the reversion of any licensed
intellectual property granted to Janssen upon the termination of the agreement.

On February 27, 2019, in connection with a private placement, the Company issued 2,898,550 ordinary shares to
JJDC, the investment arm of Johnson & Johnson and owner of Janssen, on the same terms and conditions as the other
investors in the offering. After the offering, JJDC became a related party. On November 9, 2022, the Company entered
into a securities purchase agreement with JJDC, pursuant to which the Company, in a private placement, agreed to
issue and sell to JJDC an aggregate of 3,742,514 ordinary shares at a purchase price of $6.68 per share, for gross
proceeds of approximately $25.0 million.

Clinical IRD Product Candidates

Under the Collaboration Agreement, the Company and Janssen will jointly develop Clinical IRD Product Candidates
to permit Janssen to commercialize such Clinical IRD Product Candidates under an exclusive license from the
Company. In general, the Company will have the primary responsibility to develop each Clinical IRD Product
Candidate in accordance with the development plan for each Clinical IRD Product Candidate, including where
applicable, conducting any necessary research in order to submit the applicable regulatory filings to regulatory
authorities. The Company will manufacture these products in its cGMP manufacturing facilities for both clinical and
commercial supply. Janssen will pay 100% of the clinical and commercialization costs of the products and the
Company is eligible to receive untiered 20% royalties on net sales of products and additional development and
commercialization milestones up to $340.0 million.  The Company received its first milestone payment of $30.0
million in December 2021.

MEIRAGTX HOLDINGS PLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Research IRD Product Candidates

Under the Collaboration Agreement, the Company and Janssen will collaborate to develop Research IRD Product
Candidates, with Janssen paying for the majority of the research costs. Janssen has the right to exclusively license any
product coming out of the collaboration at the time of an investigational new drug application for an additional fee for
each Research IRD Product Candidate. Janssen will then pay 100% of the clinical and commercialization costs for
these Research IRD Product Candidates and the Company will receive an untiered royalty on net sales in the high
teens as well as development milestones for each Research IRD Product Candidate.

Revenue Recognition under the Collaboration Agreement

The Collaboration Agreement is accounted for under ASC 808, however, ASC 808 does not address recognition or
measurement matters. Therefore, the Company will account for the recognition and measurement of consideration
under ASC 606. In determining the appropriate amount of revenue to be recognized under ASC 606, the Company
performed the following steps: (i) identified the promised goods or services in the contract; (ii) determined whether the
promised goods or services are performance obligations including whether they are distinct in the context of the
contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation
of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company
satisfies each performance obligation. The Company evaluated the potential performance obligations in the contract,
which included the exclusive license to Clinical IRD Product Candidates, the research, development and
manufacturing services (“the services”), and the participation in various joint committees and determined that none of
the performance obligations by themselves were distinct. Goods and services that are not distinct are bundled with
other goods or services in the contract until a bundle of goods or services that is distinct is created. The services, when
combined with the licenses, represent a bundle and should be accounted for as a single performance obligation due to
the relevance of the services to the value of the early-stage license and the potential for the intellectual property to be
significantly modified during the services period. The Company also evaluated whether or not the right to purchase
exclusive option rights for specified Research IRD Product Candidates represents future performance obligations and
concluded that these represent a separate buyer decision at market rates, rather than a material right performance
obligation. As such, these options have been excluded from the initial allocation of transaction price and the Company
will account for these options as separate contracts when and if Janssen elects to exercise the options.

Under ASC 606, the Company recognized collaboration revenue using the cost-to-cost input method, which it believes
best depicts the transfer of control to the customer. Under the cost-to-cost input method, the extent of progress towards
completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying
the combined performance obligation by the potential product candidate. Under this method, revenue is being recorded
as a percentage of the estimated transaction price based on the extent of progress towards completion. Under ASC 606,
the estimated transaction price includes variable consideration subject to constraints. The Company does not include
variable consideration to the extent that it is probable that a significant reversal in the amount of cumulative revenue
recognized will occur when any uncertainty associated with the variable consideration is resolved. The estimate of the
Company’s measure of progress and estimate of variable consideration to be included in the transaction price will be
updated at each reporting date as a change in estimate. The amount related to the unsatisfied portion will be recognized
as that portion is satisfied over time.

Under ASC 606 the Company accounts for (i) the licenses it conveyed with respect to the Clinical IRD Product
Candidates and (ii) its obligations to perform services as a single performance obligation under the Collaboration
Agreement with Janssen on a product candidate basis. Janssen’s right to purchase exclusive options to obtain certain
development, manufacturing and commercialization rights are accounted for separately as they do not represent
material rights, based on the criteria of ASC 606. Upon the exercise of any purchased option by Janssen, the contract
promises associated with an Option Target would use a separate cost-to-cost model for purposes of revenue
recognition under ASC 606.

During the year ended December 31, 2019, the Company received a $100.0 million non-refundable upfront fee from
Janssen and during the year ended December 31, 2021, the Company received a $30.0 million milestone payment. The
Company allocated these amounts plus other variable consideration not subject to constraint to each identified
performance obligation using a combination of methods allowable under ASC 606. The Company applies the practical
expedient in Topic 606 and does not include disclosures regarding amounts for variable consideration allocated to
wholly-unsatisfied performance obligations or wholly-unsatisfied distinct goods that form part of a single performance
obligation, if any. This variable consideration includes expected reimbursement of research and development costs.

During the years ended December 31, 2022 and 2021, the Company recognized $15.9 million and $37.7 million,
respectively, of the deferred revenue – related party as license revenue.

The Company also recognized $73.3 million and $69.0 million during the years ended December 31, 2022 and 2021,
respectively, related to the reimbursement of research and development expenses.

As of December 31, 2022, the Company expects to recognize the remaining $42.6 million in deferred revenue
associated with the non-refundable upfront fee and milestone payment over the estimated research and development
period using the cost-to-cost input method over an estimated period of approximately 2.9 years.

On August 2, 2022 the Company, and the Subsidiary Guarantors, entered into the Financing Agreement with
Perceptive. On December 19, 2022, the Financing Agreement was converted to a Note Purchase Agreement between
the same parties and under substantially the same terms and conditions as the Financing Agreement, subject to certain
customary note constitution terms.

The Note Purchase Agreement provides for an initial $75.0 million notes issuance (the “Tranche 1 Notes”), and the
Company may request an additional $25.0 million notes issuance to be made available at Perceptive’s sole discretion
before August 2, 2024 (the “Tranche 2 Notes”, together with the Tranche 1 Notes, the “Notes”). The Note Purchase
Agreement matures on August 2, 2026 and is interest-only during the term. The Company has the option to redeem
outstanding principal notes at any time along with an applicable early redemption fee. Outstanding amounts under the
Note Purchase Agreement bear interest at a fluctuating rate per annum equal to 10.00% plus the secured overnight
financing rate administered by the Federal Reserve Bank of New York for a one-month tenor, subject to a 1.00% floor.
The annual interest rate was 13.02% at December 31, 2022. As of December 31, 2022, the outstanding balance of the
Tranche 1 Notes was $75.0 million plus accrued interest of $4.0 million. During the year ended December 31, 2022,
the Company recorded interest expense of $4.0 million.

The Company’s obligations under the Note Purchase Agreement are secured by the Company’s London, UK and
Shannon, Ireland manufacturing facilities, $3.0 million of the Company’s cash and the bank accounts of the Subsidiary
Guarantors, and the issued and outstanding equity interests of the Subsidiary Guarantors.

The Note Purchase Agreement imposes covenants that include, among other things, enrolling in a Phase III trial for
AAV-RPGR on or before June 30, 2023, and ensuring the Company’s Shannon manufacturing facility meets or
satisfies all applicable good manufacturing practice requirements on or before December 31, 2023, as well as various
restrictions on the Company and the Subsidiary Guarantors, including restrictions pertaining to: (i) the incurrence of
additional indebtedness, (ii) limitations on liens, (iii) limitations on certain investments, (iv) making distributions,
dividends and other payments, (v) mergers, consolidations and acquisitions, (vi) dispositions of assets, (vii) the
Company’s maintenance of at least $3.0 million in a U.S. bank account, (viii) transactions with affiliates, (ix) changes
to governing documents, (x) changes to certain agreements and leases and (xi) changes in control; however, certain of
these restrictions contain exceptions which allow the Company to license, sell and monetize assets in its AAV-hAQP1
program in development to treat radiation-induced xerostomia, its AAV-GAD program in development to treat
Parkinson’s disease and its gene regulation platform technologies.

In connection with entering into the Financing Agreement, the Company granted warrants to Perceptive to purchase up
to (i) 400,000 ordinary shares of the Company at an exercise price of $15.00 per share and (ii) 300,000 ordinary

F-35

 
 
 
 
 
Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

shares of the Company at an exercise price of $20.00 per share. The warrants are exercisable immediately and expire
on August 2, 2027. The Company recorded a debt discount of $2.3 million for the allocated fair value of the warrants.

The Company also capitalized certain lender and legal costs associated with the Note Purchase Agreement totaling
$2.2 million, which were recorded as a discount to the loan. The aggregate discount of $4.4 million is being amortized
to interest expense over the term of the Note Purchase Agreement. The Company amortized $0.4 million of the
discount to interest expense during the year ended December 31, 2022. At December 31, 2022, the remaining
unamortized discount was $4.0 million.

15.  Commitments and Contingencies

There were no new material commitments or contingencies entered into during the year ended December 31, 2022.

16.  Employee Benefit Plans

United States

On January 1, 2017, Meira LLC adopted a defined contribution retirement plan that complies with Section 401(k) of
the Internal Revenue Code. All Meira LLC employees over the age of 21 are eligible to participate in the plan after
three consecutive months of service. Employees are able to defer a portion of their pay into the plan on the first day of

ITEM 9A.

CONTROLS AND PROCEDURES

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and 

procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired 
control objectives.  In addition, the design of disclosure controls and procedures must reflect the fact that there are resource 
constraints and that management is required to apply judgment in evaluating the benefits of possible controls and 
procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (principal executive officer) and Chief 

Financial Officer (principal financial officer), evaluated, as of the end of the period covered by this Form 10-K, the 
effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities 
Exchange Act of 1934, as amended (the “Exchange Act”)).  Based on that evaluation, our Chief Executive Officer 
(principal executive officer) and Chief Financial Officer (principal financial officer) concluded that our disclosure controls 
and procedures were effective at the reasonable assurance level at the end of the period covered by this Form 10-K.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as

defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is a process designed under the
supervision of our Chief Executive Officer and Chief Financial Officer, and affected by our board of directors,
management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of our financial statements for external reporting purposes in accordance with U.S. GAAP and includes policies
and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of our assets, (ii) provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being
made only in accordance with authorizations of our management and directors and (iii) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect

misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls
may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures
may deteriorate.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022.

In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the
Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based on its assessment and those
criteria, management has concluded that we maintained effective internal control over financial reporting as of December
31, 2022.

Exemption from Attestation Report of the Registered Public Accounting Firm on Internal Control Over Financial
Reporting

This Form 10-K does not include an attestation report on our internal control over financial reporting from our
independent registered public accounting firm since we qualify as an “emerging growth company” as defined under the
JOBS Act.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-

15(f) under the Exchange Act) during the quarter ended December 31, 2022 that have materially affected, or are reasonably
likely to materially affect, our internal control over financial reporting.

(1) In connection with our IPO, we assumed the 2016 Plan. As the 2016 Plan was previously approved by our

shareholders and, as we will not make future grants or awards under these plans, it is listed as “approved by
shareholders.” As such, the securities remaining available under the 2016 Plan have been excluded from the table
above.

(2) Pursuant to the terms of the 2018 Plan, the number of ordinary shares available for issuance under the 2018 Plan

automatically increases on each January 1, until and including January 1, 2028, by an amount equal to the lesser of:
(a) 4% of the aggregate number of ordinary shares outstanding on the final day of the immediately preceding
calendar year and (b) such smaller number of ordinary shares as is determined by our board of directors.

(3) The weighted average exercise price of outstanding awards does not take into account the shares issuable upon vesting 

of outstanding restricted share units which have no exercise price.  At December 31, 2022 there were a total of 
2,182,500 shares subject to restricted share units included in the Number of Securities to be Issued Upon Exercise of 
Outstanding Options, Warrants and Rights.

(4) Pursuant to the terms of the 2018 ESPP, the number of ordinary shares available for issuance under the 2018 ESPP
automatically increases on each January 1, until and including January 1, 2028, by an amount equal to the lesser of:
(a) 1% of the aggregate number of ordinary shares outstanding on the final day of the immediately preceding
calendar year and (b) such smaller number of ordinary shares as is determined by our board of directors, subject to the
limit set forth in the 2018 ESPP.

Amended  and  Restated  Note  Purchase  Agreement  and  the  Note  Documents  as  in  effect  on  and  after  the
Restatement  Effective  Date.  Each  Obligor  hereby  consents  to  the  modifications  made  to  the  Credit  Agreement
pursuant  to  this  Amendment  and  the  Amended  and  Restated  Note  Purchase  Agreement  and  hereby  agrees  that,
upon the occurrence of the Restatement Effective Date, and except as otherwise expressly set

forth  herein  or  in  the  Amended  and  Restated  Note  Purchase  Agreement,  each  Note  Document  to  which  it  is  a
party is and shall continue to be in full force and effect and the same are hereby ratified in all respects.

SECTION 2.02. Each Obligor hereby acknowledges and agrees that the Guaranteed Obligations will include all

Obligations.

SECTION  2.03.  To  induce  the  Administrative  Agent  and  the  Lender  party  hereto  to  execute  and  deliver  this
Amendment, each Obligor party hereto represents and warrants to the Administrative Agent and the Lender party
hereto that as of the date hereof, each of the following statements are true and correct:

(a)

The representations and warranties made by each Obligor party hereto herein, in the Amended and
Restated Note Purchase Agreement and each other Note Document are true and correct in all material respects as
if made on and as of such date (or in the case of any representation or warranty qualified by materiality, Material
Adverse Effect or similar qualification, true and correct in all respects) unless stated to relate solely to an earlier
date, in which case such representations or warranties shall be true and correct in all material respects as of such
earlier date.

(b)

The execution, delivery and performance of this Amendment by each Obligor party hereto, and the
resulting  amendment  and  restatement  of  the  Credit  Agreement,  have  been  duly  authorized  by  all  necessary
corporate or other organizational action on the part of such Obligor, and this Amendment and the Amended and
Restated  Note  Purchase  Agreement  each  constitutes  a  legal,  valid  and  binding  agreement  of  such  Obligor,
enforceable against such Obligor in accordance with its respective terms, except as enforcement may be limited
by  (i)  bankruptcy,  insolvency,  reorganization,  moratorium  or  similar  laws  of  general  applicability  affecting  the
enforcement  of  creditors’  rights  generally;  (ii)  general  principles  of  equity  (regardless  of  whether  such
enforceability  is  considered  in  a  proceeding  in  equity  or  at  law);  and  (iii)  solely  in  respect  of  the  English
Guarantor and the Irish Subsidiary Guarantor, the Legal Reservations and the Perfection Requirements.

(c)

The execution, delivery and performance of this Amendment by any Obligor party hereto, and the
resulting amendment and restatement of the Credit Agreement, does not (i) violate or conflict with any Law, (ii)
result in the creation or imposition of any Lien (other than Permitted Liens) on any asset of such Obligor or any of
its Subsidiaries or (iii) violate, or result in a default under, any Material Agreement binding upon such Obligor or
any  of  its  Subsidiaries  that,  in  the  case  of  clause  (i)  and  (iii)  above,  individually  or  in  the  aggregate,  could
reasonably be expected to result in a Material Adverse Effect.

(d)

No  authorization  or  approval  or  other  action  by,  and  no  notice  or  filing  with,  any  Governmental
Authority or any other Person (other than those that have been duly obtained or made and which are in full force
and effect) is required for the due execution, delivery and

2

performance by any Obligor party to this Amendment or the amendment and restatement of the Credit Agreement.

(e)

Immediately  before  and  after  giving  effect  to  this  Amendment,  no  event  has  occurred  and  is

continuing that constitutes an Event of Default.

the word “from” when used in connection with a period of time means “from and including” and

the word “until” means “to but not including”;

(h)

the  words  “asset”  and  “property”  shall  be  construed  to  have  the  same  meaning  and  effect  and  to
refer broadly to any and all assets and properties, whether tangible or intangible, real or personal, including cash,
securities, rights under contractual obligations and permits and any right or interest in any such assets or property;

(i)

accounting  terms  not  specifically  defined  herein  (other  than  “property”  and  “asset”)  shall  be

construed in accordance with GAAP;

(j)

the word “will” shall have the same meaning as the word “shall”;

(k)

where any provision in this Agreement or any other Notes Document refers to an action to be taken
by  any  Person,  or  an  action  which  such  Person  is  prohibited  from  taking,  such  provision  shall  be  applicable
whether such action is taken directly or indirectly;

(l)

on  a  day  which  is  not  a  Business  Day,  then  such  required  payment  date  shall  be  extended  to  the  immediately
following  Business  Day.  For  the  purposes  of  calculations  made  pursuant  to  the  terms  of  this  Agreement  or
otherwise for purposes of compliance herewith, GAAP will be deemed to treat operating leases as set forth in the

characterized  as  an  operating  lease  under  Accounting  Standards  Codification  Topic  No.  840,  Leases,  shall  be
accounted for as an operating lease (and not as a capital lease or otherwise reflected on the Issuer’s consolidated
balance  sheet)  for  purposes  of  this  Agreement  regardless  of  the  implementation  of  Accounting  Standards
Codification  Topic  No.  842,  Leases,  or  any  change  in  GAAP  following  the  Closing  Date  that  would  otherwise
require such lease to be characterized or re-characterized (on a prospective or retroactive basis or otherwise) as a
capital lease.

division under Delaware law (or any comparable event under a different jurisdiction’s laws): (i) if any asset, right,
obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it
shall be deemed to have been transferred from the original Person to the subsequent Person, and (ii) if any new
Person  comes  into  existence,  such  new  Person  shall  be  deemed  to  have  been  organized  on  the  first  date  of  its
existence by the holders of its Equity Interests at such time.

1.05 Reference Rate Replacement. Upon the occurrence of an event of the type described in the definition of
“Reference Rate Transition  Event”,  the Administrative  Agent  will  promptly  notify  the  Issuer  thereof  and  as  set

in good faith, to establish an alternate rate of interest to One-Month Term SOFR.

1.06 Times of Day; Times of Performance.

(a)

Unless otherwise specified, all references herein to times of day shall be references to New York

City time (daylight or standard, as applicable).

(b)

which is not a Business Day, then such due date shall be extended to the immediately following Business Day.

1.07 Rates.  The  Administrative  Agent  does  not  warrant  or  accept  responsibility  for,  and  shall  not  have  any
liability with respect to (a) the continuation of, administration of, submission of, calculation of or any other matter
related  to  the  Term  SOFR  Reference  Rate  or  One-Month  Term  SOFR,  or  any  component  definition  thereof  or
rates  referred  to  in  the  definition  thereof,  or  any  alternative,  successor  or  replacement  rate  thereto,  including
whether the composition or characteristics of any such alternative, successor or replacement rate will be similar to,
or produce the same value or economic equivalence of, or have the same volume or liquidity as, the Term SOFR
Reference  Rate  or  One-Month  Term  SOFR  prior  to  its  discontinuance  or  unavailability,  or  (b)  the  effect,
implementation  or  composition  of  any  Conforming  Changes.  There  is  no  assurance  that  the  composition  or
characteristics of any such alternative, successor or replacement Reference Rate will be similar to or produce the
same value or economic equivalence as One-Month Term SOFR or that it will have the same volume or liquidity
as  did  One-Month  Term  SOFR  prior  to  its  discontinuance  or  unavailability.  The  Administrative  Agent  and  its
affiliates  or  other  related  entities  may  engage  in  transactions  that  affect  the  calculation  of  the  Term  SOFR
Reference  Rate  or  One-Month  Term  SOFR,  any  alternative,  successor  or  replacement  rate  or  any  relevant
adjustments thereto, in each case, in a manner that is adverse to the Issuer. The Administrative Agent may select
information sources or services in its reasonable discretion to ascertain the Term SOFR Reference Rate or One-
Month Term SOFR, in each case pursuant to the terms of this Agreement, and shall have no liability to the Issuer,
any  Noteholder  or  any  other  Person  for  damages  of  any  kind,  including  direct  or  indirect,  special,  punitive,
incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether
at law or in equity),  for  any  error  or  calculation  of  any  such  rate  (or  component thereof) provided by any such
information source or service.

SECTION 2
THE COMMITMENTS AND THE NOTES

2.01

Issuance of Notes.

(a)

The parties to this Agreement acknowledge and agree that, prior to the amendment and restatement
of  this  Agreement  as  of  the  Amendment  and  Restatement  Date,  this  Agreement  provided  for  the  borrowing  of
certain loans, and such loans (in the aggregate principal amount of $75,000,000) were borrowed by the Issuer and,
immediately  following  such  amendment  and  restatement,  $75,000,000  in  aggregate  principal  amount  remains
outstanding under this Agreement as the Tranche 1 Notes pursuant to Section 2.01(b) below.

(b)

Accordingly,  on  the  terms  and  subject  to  the  conditions  of  this  Agreement,  (i)  each  Noteholder
subscribed  for  the  Tranche  1  Notes,  and  the  Issuer  issued  such  Tranche  1  Notes,  on  the  Closing  Date  in  an
aggregate  principal  amount  for  all  Noteholders  in  an  aggregate  amount  of  $75,000,000  and  (ii)  in  the  sole
discretion  of  the  Majority  Noteholders,  during  the  Tranche  2  Notes  Draw  Period,  the  Issuer  may  request  the
subscription  by  the  Noteholders  of  the  Tranche  2  Notes  in  an  aggregate  amount  not  to  exceed  the  Tranche  2
Maximum Issue Amount.

(c)

No amount paid, repaid or prepaid by the Issuer or any Guarantor with respect to any Note may be

required to be subscribed or readvanced under the Notes Documents.

(d)

Any term or provision hereof (or of any other Notes Document) to the contrary notwithstanding,

Notes issued and the subscriptions hereunder will be denominated solely in Dollars and no other currency.

2.02

[Reserved].

2.03 Noteholder Representations. Each Noteholder hereby represents and warrants to the Issuer that:

(a)

The Noteholder is, and on the Closing Date was, (i) an “accredited investor” as that term is defined
in Rule 501(a) of Regulation D under the Securities Act and (ii) a “qualified institutional buyer” (as that term is
defined in Rule 144A of the Securities Act). The Noteholder is acquiring, or acquired on the Closing Date, the
Notes for investment for its own account and not with a current view towards, or for resale in connection with, the
public sale or distribution of the Notes, except pursuant to sales registered or exempted under the Securities Act.

(b)

The  Noteholder  understands  and  acknowledges  that  the  Notes  issued,  or  to  be  issued,  are

“restricted securities” under the Securities Act inasmuch as they are being acquired

38

from  the  Company  in  a  transaction  not  involving  a  public  offering  and  that,  under  such  Laws  and  applicable
regulations,  such  securities  may  be  resold  without  registration  under  the  Securities  Act  only  in  certain  limited
circumstances.  In  addition,  the  Holder  represents  that  it  is  familiar  with  Rules  144  and  144A,  as  presently  in
effect, and understands the resale limitations imposed thereby and by the Securities Act.

(c)

The Noteholder acknowledges that it can bear the economic and financial risk of its investment for
an indefinite period and has such knowledge and experience in financial or business matters that it is capable of
evaluating  the  merits  and  risks  of  the  investment  in  the  Notes.  The  Noteholder  has  had  an  opportunity  to  ask
questions and receive answers from the Issuer regarding the terms and conditions of the Notes and the business,
properties, prospects and financial condition of the Issuer.

2.04 Use  of  Proceeds.  The  Issuer  shall  use  the  proceeds  of  the  issuance  of  Notes  for  working  capital  and
general corporate purposes, including the payment of fees and expenses associated with this Agreement and the
other Notes Documents and the transactions contemplated hereby and thereby.

2.05 Constitution of the Notes. The Notes will be:

(a)

(b)

14.05(d); and

issued in a minimum amount of $1,000,000 and integral multiples thereof;

considered  issued  when  their  details  are  registered  in  the  Notes  Register  referred  to  in  Section

(c)

subject to the terms and conditions of this Agreement.

Signing and authenticating Notes Certificates. A Notes Certificate shall not be considered to have been

2.06
issued unless and until it has been signed by the Issuer and authenticated by the Administrative Agent.

Status  of  Notes  Certificate.  A  Notes  Certificate  shall  serve  as  evidence  of  the  relevant  records  in  the
2.07
Notes Register and shall not represent title to the Notes. In the event of a conflict between information in a Notes
Certificate and information in the Notes Register, the information in the Notes Register will prevail.

Stocks of blank Notes Certificates. The Issuer shall execute and deliver to the Administrative Agent such
2.08
number  of  blank  Notes  Certificates,  duly  signed  by  it,  as  the  Administrative  Agent  may  from  time  to  time
reasonably require.

2.09 Delivery  of  replacements.  Subject  to  receipt  of  sufficient  blank  Notes  Certificates,  the  Administrative
Agent  shall,  upon  and  in  accordance  with  the  instructions  of  the  Issuer  (which  instructions  may,  without
limitation, include terms as to the payment of expenses and as to

39

evidence, security and indemnity), complete, authenticate and deliver replacement Notes Certificates.

2.10 Replacement  Notes  Certificates.  The  Administrative  Agent  shall  not  deliver  or  issue  any  replacement
Notes Certificate:

(a)

if  the  Notes  Certificate  being  replaced  has  been  mutilated  or  defaced  otherwise  than  against  the

surrender of the same; and

(b)

until the claimant of the Notes Certificate has:

(i)

provided to the Administrative Agent such evidence, security and indemnity as the Issuer

and/or Administrative Agent may reasonably require; and

(ii)

paid such costs and expenses as may be incurred in connection with such replacement.

2.11 Replacements to be numbered. Each replacement Notes Certificate shall bear a unique serial number.

2.12 Cancellation  and  destruction.  The  Administrative  Agent  shall  cancel  and  destroy  each  mutilated  or
defaced Notes Certificate surrendered to it in respect of which a replacement Notes Certificate has been delivered.

2.13 Notification.  The  Administrative  Agent  shall  notify  the  Issuer  of  the  delivery  by  it  of  any  replacement
Notes Certificate surrendered to it in respect of which a replacement Notes Certificate has been delivered.

2.14 Legend. The Notes may only be transferred or disposed of in compliance with applicable state and federal
securities Laws. For so long as such restrictions apply, the Noteholder agrees to the imprinting of a legend in the
Note Register and on the Notes in the following form: THIS NOTE HAS NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) OR UNDER THE SECURITIES LAWS OF
CERTAIN  STATES,  AND  MAY  NOT  BE  SOLD,  OFFERED  FOR  SALE,  PLEDGED,  CHARGED,
HYPOTHECATED  OR  OTHERWISE  TRANSFERRED  EXCEPT  PURSUANT  TO  AN  EFFECTIVE
REGISTRATION STATEMENT FILED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS
OR  PURSUANT  TO  AN  AVAILABLE  EXEMPTION  FROM  REGISTRATION  UNDER  THE  ACT  AND
APPLICABLE  STATE  SECURITIES  LAWS  OR  UNLESS  SOLD  IN  ACCORDANCE  WITH  RULE  144
UNDER THE ACT.

SECTION 3
PAYMENTS, REDEMPTION AND INTEREST

3.01

Payments and Redemption Generally; Application.

(a)

There will be no scheduled redemptions of principal on the Notes prior to the Maturity Date.

40

(b)

On the Maturity Date, the Issuer shall redeem the entire remaining outstanding principal amount of

the Notes at par in full and in cash.

(c)

The Issuer agrees that all amounts payable hereunder or under any other Notes Document, whether
in respect of any Notes, fees or interest accrued or accruing thereon, or any other Obligations, shall be paid, repaid
and prepaid, as the case may be, solely in Dollars and no other currency pursuant to the terms of this Section 3.
Except as otherwise provided in this Agreement, proceeds of each payment (including each redemption of Notes)
by  the  Issuer  shall  be,  and  shall  be  deemed  to  be,  made  ratably  to  the  Noteholders  in  accordance  with  their
respective Proportionate Shares.

3.02

Interest.

(a)

Interest Generally. The outstanding principal amount of the Notes, as well as the amount of all
other  outstanding  Obligations,  shall  accrue  interest  at  the  Interest  Rate  on  and  from  the  Closing  Date.  The
Administrative Agent’s determination of the Interest Rate shall be binding on the Issuer, its Subsidiaries and the
Noteholders in the absence of manifest error.

(b)

Default Interest. Notwithstanding the foregoing, unless the Administrative Agent otherwise agrees
in writing, upon the occurrence and during the continuance of any Event of Default, the Applicable Margin shall
increase  automatically  by  three  percent  (3.0%)  per  annum  (the  Interest  Rate,  as  increased  pursuant  to  this
Section 3.02(b), being the “Default Rate”). If any Obligation is not paid when due under any applicable Notes
Document, the amount thereof shall accrue interest at the Default Rate. For the avoidance of doubt, the Default
Rate shall not be cumulative and no more than three percent (3.00%) per annum can be applicable to the Notes or
any past due Obligation at any time, and further for the avoidance of doubt, once an Event of Default is waived by
the Administrative Agent or the Majority Noteholders, the Default Rate shall cease to apply.

(c)

Interest  Payment  Dates.  Accrued  interest  on  the  Notes  shall  be  payable  in  cash,  in  arrears,  on
each  Payment  Date  with  respect  to  the  most  recently  completed  Interest  Period,  and  upon  the  payment  or
redemption of the Notes (on the principal amount being so paid or redeemed); provided that interest payable at the
Default Rate, or any accrued interest not paid on or before the Maturity Date, shall be payable from time to time
in cash on the Administrative Agent’s demand until paid in full.

(d)

Conforming Changes. In  connection  with  the  use  or  administration  of  One-Month  Term  SOFR,
the  Administrative  Agent  will  have  the  right  to  make  Conforming  Changes  from  time  to  time  and,
notwithstanding anything to the contrary herein or in any other Notes Document, any amendments implementing
such Conforming Changes will become effective without any further action or consent of any other party to this
Agreement  or  any  other  Notes  Document.  The  Administrative  Agent  will  promptly  notify  the  Issuer  and  the
Noteholders of the effectiveness of any Conforming Changes in connection with the use or administration of One-
Month Term SOFR.

(e)

Compensation for Loss. In the event of the payment or redemption of any principal of any Note
other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default),
then, in any such event, the Issuer shall compensate each

41

Noteholder for any  reasonable  and  documented  loss,  cost  and  expense  attributable to such event, including any
reasonable  and  documented  loss,  cost  or  expense  arising  from  the  liquidation  or  redeployment  of  funds.  A
certificate of any Noteholder including documentary evidence of any amount or amounts that such Noteholder is
entitled to receive pursuant to this Section shall be delivered to the Issuer and shall be conclusive absent manifest
error. The Issuer shall pay such Noteholder the amount shown as due on any such certificate within 30 days after
receipt thereof.

(f)

Listing and Co-operation Obligations. The parties agree to co-operate in good faith to ensure that
the  Notes  are  listed  on  a  Recognised  Stock  Exchange  promptly  after  the  date  of  this  Agreement,  and  to  use
commercially  reasonable  best  efforts  to  assist  the  Obligors  to  obtain  and  maintain  a  listing  of  such  Notes  on  a
Recognised Stock Exchange such that the exemption from UK withholding tax under section 882 of the UK ITA
(“QEB Exemption”) applies. If the Notes are not listed on a Recognised Stock Exchange within six months after
the  date  of  this  Agreement,  or  if  the  QEB  Exemption  is  otherwise  unavailable,  each  Noteholder  shall  use  all
commercially reasonable best efforts to ensure that the Issuer is able to make payments to that Noteholder, to the
maximum extent possible, without a UK Tax Deduction, including the completion of any procedural formalities
necessary for the Issuer to obtain authorization to make such payments without a UK Tax Deduction; provided,
however, that notwithstanding anything to the contrary in this Agreement, (i) Perceptive Credit Holdings III, LP
shall  not  be  obligated  to  take  any  actions  that  would  (x)  disclose  the  identity  of  its  partners,  or  (y)  be
disadvantageous to its interests hereunder or under any other Notes Document in any material respect, and (ii) as
provided pursuant to Section 14.03 hereof, the Issuer shall reimburse Perceptive Credit Holdings III, LP for all
reasonable  costs  and  expenses  incurred  by  it  in  connection  with  actions  taken  by  it  pursuant  to  this  Section
3.02(f). Any conversion of the existing indebtedness which shall comprise the Notes issued under this Agreement
or any equivalent transaction will be conducted pursuant to a valid exemption from the registration and prospectus
delivery  requirements  under  the  Securities  Act  and  the  qualification  requirements  under  applicable  state  and
foreign  Law  and  otherwise  in  compliance  with  the  securities  Laws  of  the  United  States.  Any  costs  arising  in
connection with the listing shall be borne by the Obligors.

(g)

Interest  Deferral.  Notwithstanding  any  other  provision  of  this  Agreement,  the  payment  of  any
interest in respect of the Notes shall automatically be deferred, at no additional cost to the Obligors, in respect of
all  Payment  Dates,  until  the  first  Payment  Date  following  the  earlier  of:  (i)  the  date  the  Issuer  receives
confirmation that the Notes have been listed on a Recognised Stock Exchange; and (ii) February 2, 2023.

3.03 Early Redemption; Early Redemption Premium.

(a)

Optional Redemption of Notes

(i)

Subject to prior written notice pursuant to clause (a)(ii) below and the applicable portion of
the payment of the Early Redemption Fee pursuant to clause (c) below, the Issuer shall have the right to optionally
redeem, in whole or in part, the outstanding principal amount of the Notes at par on any Business Day (an “Early
Redemption Date”); provided that in addition to such redeemed principal amount and the Early Redemption Fee
applicable to such redeemed principal amount, the Issuer shall also make payment in full in cash on such Early
Redemption Date the applicable portion of all accrued but unpaid interest on the principal amount

42

of the Notes being redeemed (such aggregate amount of Early Redemption Fee, redeemed principal and accrued
interest being herein referred to as the “Early Redemption Price”).

(ii)

A  notice  of  optional  redemption  shall  be  effective  only  if  received  by  the  Administrative
Agent  not  later  than  2:00  p.m.  (New  York  City  time)  on  a  date  at  least  three  (3)  (but  not  more  than  five  (5))
Business Days prior to the proposed Early Redemption Date. Each notice of optional redemption shall specify the
proposed  Early  Redemption  Date  (and  may  be  revocable),  the  principal  amount  of  the  Notes  to  be  prepaid,  the
amount of accrued and unpaid interest that will be paid on the Early Redemption Date, and, in reasonable detail, a
calculation  of  the  Early  Redemption  Fee  payable  on  such  Early  Redemption  Date  in  connection  with  such
proposed redemption.

(b) Mandatory  Redemptions.  Within  ten  (10)  Business  Days  of  the  receipt  of  Net  Cash  Proceeds
from  the  occurrence  of  any  Casualty  Event  or  Asset  Sale  (other  than  any  Asset  Sale  permitted  pursuant  to
Sections 9.09 (a), (b), (c), (d), (e), (g), (j) and (k)), to the extent that the aggregate amount of Net Cash Proceeds
received by Issuer and its Subsidiaries (and not paid to the Administrative Agent as a redemption of the Notes) in
respect of all such Casualty Events or Asset Sales, when taken together, exceeds $2,500,000 in any fiscal year, the
Issuer  shall  apply  an  amount  equal  to  one  hundred  percent  (100%)  of  the  Net  Cash  Proceeds  received  by  the
Issuer or any of its Subsidiaries with respect to such Casualty Event or Asset Sale, as the case may be with such
amount of Net Cash Proceeds being allocated, to (i) the redemption of principal outstanding under the Notes, and
(ii)  the  payment  of  accrued  and  unpaid  interest  on  such  principal  amount  of  the  Notes  being  prepaid  and  the
payment  of  the  applicable  portion  of  the  Early  Redemption  Fee  being  paid.  Such  Net  Cash  Proceeds  shall  be
allocated to such redemption and payments such that the full amount of the applicable Early Redemption Price
shall  be  paid  with  such  Net  Cash  Proceeds.  Notwithstanding  the  foregoing,  so  long  as  no  Event  of  Default  has
occurred and is continuing or shall immediately result therefrom, if, within seven (7) Business Days following the
occurrence  of  any  such  Casualty  Event  or  Asset  Sale,  a  Responsible  Officer  of  the  Issuer  delivers  to  the
Administrative Agent a notice to the effect that the Issuer or the applicable Subsidiary intends to apply the Net
Cash  Proceeds  from  such  Casualty  Event  or  Asset  Sale  to  repair,  refurbish,  restore,  replace  or  rebuild  the  asset
subject to such Casualty Event or Asset Sale, then such Net Cash Proceeds of such Casualty Event or Asset Sale
may be applied for such purpose in lieu of such mandatory redemption otherwise required pursuant to this clause
(b)  to  the  extent  such  Net  Cash  Proceeds  of  such  Casualty  Event  or  Asset  Sale  are  actually  applied  for  such
purpose; provided that, in the event that Net Cash Proceeds have not been so applied within one hundred eighty
(180)  days  following  the  occurrence  of  such  Casualty  Event  or  Asset  Sale,  the  Issuer  shall  make  a  mandatory
redemption of the Notes in an aggregate amount equal to one hundred percent (100%) of the unused balance of
such Net Cash Proceeds received by the Issuer or any of its Subsidiaries with respect to such Casualty Event or
Asset Sale, as the case may be, together with payment of accrued and unpaid interest on the principal amount of
the  Notes  being  so  prepaid  and  the  applicable  Early  Redemption  Fee,  with  such  amount  of  Net  Cash  Proceeds
being  allocated  to  the  redemption  of  principal,  the  payment  of  accrued  and  unpaid  interest  on  such  principal
amount  of  the  Notes  being  redeemed  and  the  payment  of  the  applicable  portion  of  the  Early  Redemption  Fee
being paid such that the full payable with respect to such mandatory redemption is paid with such unused balance
of Net Cash Proceeds. Notwithstanding the foregoing, in respect of a Casualty Event relating to a Manufacturing
Facility,  to  the  extent  required  by  the  basis  of  settlement  under  any  policy  of  insurance  relating  to  that
Manufacturing Facility or pursuant to the

43

terms  of  any  lease  under  which  the  Issuer  or  any  of  its  Subsidiaries  holds  an  interest  in  that  Manufacturing
Facility,  the  Issuer  or  the  applicable  Subsidiary  shall  apply  moneys  received  under  any  policy  of  insurance  in
respect of that Manufacturing Facility towards replacing, restoring or reinstating that Manufacturing Facility.

(c)

Early  Redemption  Fee.  Without  limiting  the  foregoing,  whenever  any  redemption  of  Notes  is
made hereunder pursuant to Section 3.03(a) or Section 3.03(b), acceleration or otherwise, the applicable portion
of  the  Early  Redemption  Fee  being  paid  shall  be  due  and  payable  in  full  in  cash  on  the  applicable  Early
Redemption Date for such redemption.

(d)

Application.  Proceeds  of  any  redemption  made  pursuant  to  clauses  (a)  or  (b)  above  shall  be
applied  in  the  following  order  of  priority,  with  proceeds  being  applied  to  a  succeeding  level  of  priority  only  if
amounts owing pursuant to the immediately preceding level of priority have been paid in full in cash; provided
that  all  such  redemptions  made  to  Noteholders  shall  be  applied  pro  rata  in  accordance  with  their  respective
Proportionate Shares:

(i)

first, to the payment of that portion of the Obligations payable to the Administrative Agent
constituting fees, indemnities, costs, expenses, and other amounts then due and owing (including costs, Losses and
fees and disbursements and other charges of counsel payable under Section 14.03);

(ii)

second,  to  the  payment  of  that  portion  of  the  Obligations  payable  to  the  Noteholders
constituting fees (other than any Early Redemption Fee), indemnities, expenses, and other amounts then due and
owing  (including  fees  and  disbursements  and  other  charges  of  counsel  payable  under  Section  14.03)  ratably
among them in proportion to the respective amounts described in this clause (ii) payable to them;

(iii)

third, to the payment of any accrued and unpaid interest and any fees then due and owing;

(iv)

fourth, to the redemption of unpaid principal of the Notes of the Noteholders at par;

(v)

fifth, to the payment of any Early Redemption Fee then due and payable;

(vi)

sixth,  to  the  payment  in  full  of  all  other  Obligations  then  due  and  payable  to  the
Administrative Agent and the Noteholders, ratably among them in proportion to the respective amounts described
in this clause (vi) payable to them; and

(vii)

seventh, to the Issuer or such other Persons as may lawfully be entitled to or directed by the

Issuer to receive the remainder.

3.04
Facility Fees. The Issuer (i) paid on the Closing Date, to the Administrative Agent (for the pro rata benefit
of the Noteholders) a fee equal to [***] (the “Tranche 1 Facility Fee”) by way of deduction from the proceeds of
the  Tranche  1  Notes  issued  by  the  Issuer  by  the  Noteholders  and  (ii)  shall  pay,  on  any  Tranche  2  Notes
Subscription Date, to the Administrative Agent (for the pro rata benefit of the Noteholders) a fee equal to 0.75%
of  the  aggregate  principal  amount  of  the  Tranche  2  Notes  subscribed  for  on  such  Tranche  2  Issue  Date  (the
“Tranche 2 Facility Fee” and

44

together  with  the  Tranche  1  Facility  Fee,  the  “Facility  Fees”).  Upon  receipt  of  payment  from  the  Issuer,  the
Administrative  Agent  will  promptly  thereafter  distribute  like  funds  relating  to  any  such  payment  to  the
Noteholders pro rata on the basis of each Noteholder’s Proportionate Share. Once paid by the Issuer, such Facility
Fees shall be non-refundable.

SECTION 4

Obligors  under  this  Agreement  or  any  other  Notes  Document  shall  be  made  (i)  in  Dollars,  in  immediately
available funds, without deduction, set off or counterclaim, to the applicable Noteholder to which such payment is
owed, to the deposit account of such Noteholder designated by it by notice to the Issuer, and (ii) not later than
2:00 p.m. (New York City time) on the date on which such payment is due (each such payment made after such
time on such due date shall be deemed to have been made on the next succeeding Business Day).

(b)

Application of Payments. All such payments referenced in clause (a) above shall be applied as set

forth in Section 3.03(d) above.

(c)

Non-Business Days. If the due date of any payment under this Agreement (whether in respect of
principal, interest, fees, costs or otherwise) would otherwise fall on a day that is not a Business Day, such date
shall be extended to the next succeeding Business Day; provided that if such next succeeding Business Day would
fall after the Maturity Date, payment shall be made on the immediately preceding Business Day.

4.02 Computations. All computations of interest and fees hereunder shall be computed on the basis of a year of
three hundred and sixty (360) days and actual days elapsed during the period for which payable.

4.03

Set-Off.

(a)

Set-Off Generally. Upon the occurrence and during the continuance of any Event of Default, the
Administrative  Agent,  each  of  the  Noteholders  is  hereby  authorized  at  any  time  and  from  time  to  time,  to  the
fullest  extent  permitted  by  Law,  to  set  off  and  apply  any  and  all  deposits  (general  or  special,  time  or  demand,
provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any
time owing by the Administrative Agent, any Noteholder to or for the credit or the account of any Obligor against
any  and  all  of  the  Obligations,  whether  or  not  such  Person  shall  have  made  any  demand  and  although  such
obligations  may  be  unmatured.  Any  Person  exercising  rights  of  set  off  hereunder  agrees  to  promptly  notify  the
Issuer  after  any  such  set-off  and  application;  provided  that  the  failure  to  give  such  notice  shall  not  affect  the
validity  of  such  set-off  and  application.  The  rights  of  the  Administrative  Agent,  the  Noteholders  under  this
Section 4.03 are in addition to other rights and remedies (including other rights of set-off) that such Persons may
have.

(b)

Exercise  of  Rights  Not  Required.  Nothing  contained  in  Section  4.03(a)  shall  require  the

Administrative Agent or any Noteholder to exercise any such right or shall affect the

45

right of such Persons to exercise, and retain the benefits of exercising, any such right with respect to any other
indebtedness or obligation of any Obligor.

(c)

Payments Set Aside. To the extent that any payment by or on behalf of any Obligor is made to the
Administrative  Agent  or  any  Noteholder,  or  the  Administrative  Agent,  any  Noteholder  or  any  Affiliate  of  the
foregoing  exercises  its  right  of  setoff,  and  such  payment  or  the  proceeds  of  such  setoff  or  any  part  thereof  is
subsequently  invalidated,  declared  to  be  fraudulent,  or  preferential,  set  aside  or  required  (including  pursuant  to
any settlement entered into by the Administrative Agent, such Noteholder or such Affiliate in its discretion) to be
repaid  to  a  trustee,  receiver,  examiner  or  any  other  party,  in  connection  with  any  Insolvency  Proceeding  or
otherwise,  then  to  the  extent  of  such  recovery,  the  obligation  or  part  thereof  originally  intended  to  be  satisfied
shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not
occurred.

(d)

To the extent permitted under applicable Law, any Participant acquiring a participation pursuant to
Section 14.05(e) hereof (as well as any Noteholder acquiring a participation pursuant to Section 14.05(e) hereof)
may exercise against the Obligors rights of setoff and counterclaim with respect to such participation as fully as if
such Participant was a direct creditor of the Obligor in the amount of such participation.

SECTION 5
YIELD PROTECTION, ETC.

5.01 Additional Costs.

(a)

Changes in Law Generally. If, on or after the Closing Date (or, with respect to any Noteholder,
such  later  date  on  which  such  Noteholder  becomes  party  to  this  Agreement),  the  adoption  of  any  Law,  or  any
change in any applicable Law, or any change in the interpretation or administration thereof by any court or other
Governmental  Authority  charged  with  the  interpretation  or  administration  thereof,  or  compliance  by  the
Administrative  Agent  or  any  of  the  Noteholders  (or  the  office  to  which  any  of  its  Notes  are  booked)  with  any
request or directive (whether or not having the force of Law) of any such Governmental Authority, shall impose,
modify or deem applicable any reserve (including any such requirement imposed by the Board of Governors of
the Federal Reserve System), special deposit, contribution, insurance assessment or similar requirement, in each
case that becomes effective after the Closing Date (or, with respect to any Noteholder, such later date on which
such Noteholder becomes party to this Agreement) against assets of, deposits with or for the account of, or credit
extended by, a Noteholder (or its office to which any of its Notes are booked) or other Recipient or shall impose
on  a  Noteholder  (or  the  office  to  which  any  of  its  Notes  are  booked)  or  other  Recipient  any  other  condition
affecting  the  Notes  or  the  Commitment,  and  the  result  of  any  of  the  foregoing  is  to  increase  the  cost  to  such
Noteholder  or  such  other  Recipient  of  making  or  maintaining  the  Notes,  or  to  reduce  the  amount  of  any  sum
received or receivable by such Noteholder or other Recipient under this Agreement or any other Notes Document,
or subject any Noteholder to any Taxes on its Notes, Commitment or other obligations, or its deposits, reserves,
other  liabilities  or  capital  (if  any)  attributable  thereto  by  an  amount  reasonably  deemed  by  such  Noteholder  in
good  faith  to  be  material  (other  than  (i)  Indemnified  Taxes,  (ii)  Taxes  described  in  clauses  (ii)  and  (iii)  of  the
definition  of  “Excluded  Taxes”,  (iii)  Connection  Income  Taxes  and  (iv)  any  Bank  Levy  or  any  payment
attributable to, or

46

liability arising as a consequence of, a Bank Levy), then the Issuer shall pay to such Noteholder within three (3)
Business Days after written demand such additional amount or amounts as will compensate such Noteholder for
such increased cost or reduction.

(b)

Change  in  Capital  Requirements.  If  a  Noteholder  shall  have  determined  that,  on  or  after  the
Closing Date (or, with respect to any Noteholder, such later date on which such Noteholder becomes party to this
Agreement), the adoption of any applicable Law regarding capital adequacy, or any change therein, or any change
in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of
Law) of any such Governmental Authority, in each case that becomes effective after the Closing Date (or, with
respect  to  any  Noteholder,  such  later  date  on  which  such  Noteholder  becomes  party  to  this  Agreement),  has  or
would have the effect of reducing the rate of return on capital of a Noteholder (or its parent) as a consequence of a
Noteholder’s  obligations  hereunder  or  the  Notes  to  a  level  below  that  which  a  Noteholder  (or  its  parent)  could
have  achieved  but  for  such  adoption,  change,  request  or  directive  by  an  amount  reasonably  deemed  by  it  to  be
material,  then  the  Issuer  shall  pay  to  such  Noteholder  on  demand  such  additional  amount  or  amounts  as  will
compensate such Noteholder (or its parent) for such reduction.

(c)

Notification  by  Noteholder.  Each  Noteholder  shall  promptly  notify  the  Issuer  of  any  event  of
which it has knowledge, occurring after the Closing Date (or, with respect to any Noteholder, such later date on
which  such  Noteholder  becomes  party  to  this  Agreement),  which  will  entitle  such  Noteholder  to  compensation
pursuant to this Section 5.01. Before giving any such notice pursuant to this Section 5.01(c) such Noteholder shall
designate a different office for booking its Notes if such designation (x) will, in the reasonable judgment of such
Noteholder,  avoid  the  need  for,  or  reduce  the  amount  of,  such  compensation  and  (y)  will  not,  in  the  reasonable
judgment of such Noteholder, be materially disadvantageous to such Noteholder. A certificate of such Noteholder
claiming  compensation  under  this  Section  5.01,  setting  forth  in  reasonable  detail  the  additional  amount  or
amounts to be paid to it hereunder and also setting forth in reasonable detail the basis for calculating the additional
amounts claimed to be owed to such Noteholder, shall be conclusive and binding on the Issuer in the absence of
manifest error.

(d)

Delays  in  Requests.  Failure  or  delay  on  the  part  of  any  Noteholder  to  demand  compensation
pursuant  to  the  foregoing  provisions  of  this  Section  shall  not  constitute  a  waiver  of  such  Noteholder’s  right  to
demand such compensation; provided that the Issuer shall not be required to compensate a Noteholder pursuant to
the foregoing provisions of this Section for any increased costs unless the Noteholder notifies the Issuer within
ninety (90) days following the receipt by such Noteholder of its audited annual financial statements of the change
in Law giving rise to such increased costs or reductions and of such Noteholder’s intention to claim compensation
therefor.

(e)

Other Changes. Notwithstanding anything herein to the contrary, (x) the Dodd-Frank Wall Street
Reform  and  Consumer  Protection  Act  and  all  requests,  rules,  guidelines  or  directives  thereunder  or  issued  in
connection therewith and (y) all requests, rules, guidelines or directives promulgated by the Bank for International
Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United
States or foreign regulatory

47

authorities, in each case pursuant to Basel III, shall in each case be deemed to constitute a change in Law for all
purposes of this Section 5.01, regardless of the date enacted, adopted or issued.

5.02
Illegality. Notwithstanding any other provision of this Agreement, in the event that on or after the Closing
Date  (or,  with  respect  to  any  Noteholder,  such  later  date  on  which  such  Noteholder  becomes  party  to  this
Agreement), the adoption of or any change in any applicable Law or in the interpretation or application thereof by
any competent Governmental Authority shall make it unlawful for a Noteholder or the office to which any of its
Notes are booked to perform any of its obligations or to subscribe for or maintain its participation in any Note
(and, in the opinion of such Noteholder, the designation of a different office for the booking of its Notes would
either not avoid such unlawfulness or would be disadvantageous to such Noteholder), then such Noteholder shall
promptly notify the Issuer thereof, following which (i) such Noteholder’s Commitment shall be suspended until
such time as such Noteholder may again subscribe for and maintain its participation in the Notes hereunder and
(ii) if such Law shall so mandate, the Notes shall be redeemed by the Issuer on or before such date as shall be
mandated by such Law in an amount equal to the Early Redemption Price applicable on such Early Redemption
Date in accordance with Section 3.03(a).

5.03 Taxes.

(a)

Payments Free of Taxes. Any and all payments by or on account of any Obligations shall be made
without deduction or withholding for any Taxes, except as required by applicable Law. If any applicable Law (as
determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding
of  any  Tax  from  any  such  payment  by  a  Withholding  Agent,  then  the  applicable  Withholding  Agent  shall  be
entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the
relevant Governmental Authority in accordance with applicable Law and, if such Tax is an Indemnified Tax, then
the sum payable by such Obligor shall be increased as necessary so that after such deduction or withholding has
been made (including such deductions and withholdings applicable to additional sums payable under this Section
5.03) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction
or withholding been made.

(b)

Payment of Other Taxes by the Issuer. The Issuer shall timely pay to the relevant Governmental
Authority  in  accordance  with  applicable  Law,  or  at  the  option  of  the  Administrative  Agent  or  each  Noteholder,
timely reimburse it for the payment of any Other Taxes.

(c)

Evidence  of  Payments.  As  soon  as  reasonably  practicable  after  any  payment  of  Taxes  by  the
Issuer to a Governmental Authority pursuant to this Section 5, the Issuer shall deliver to the Administrative Agent
the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a
copy  of  the  return  reporting  such  payment  or  other  evidence  of  such  payment  reasonably  satisfactory  to  the
Administrative Agent.

(d)

Indemnification by the Issuer. The Issuer shall reimburse and indemnify each Recipient, within
ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes
imposed or asserted on or attributable to amounts payable under this Section 5) payable or paid by such Recipient
or  required  to  be  withheld  or  deducted  from  a  payment  to  such  Recipient  and  any  reasonable  expenses  arising
therefrom or with respect thereto,

48

whether  or  not  such  Indemnified  Taxes  were  correctly  or  legally  imposed  or  asserted  by  the  relevant
Governmental  Authority,  but  excluding,  for  the  avoidance  of  doubt,  any  Indemnified  Tax  which  is  suffered  or
incurred in respect of any Bank Levy, or any payment attributable to, or liability arising as a consequence of, a
Bank Levy.  A  certificate  as  to  the  amount  of  such  payment  or  liability  delivered  to  the  Issuer  by  a  Noteholder
(with  a  copy  to  the  Administrative  Agent),  or  by  the  Administrative  Agent  on  its  own  behalf  or  on  behalf  of  a
Noteholder shall be conclusive absent manifest error.

(e)

indemnify 

the
Indemnification  by  the  Noteholders.  Each  Noteholder  shall  severally 
Administrative  Agent,  within  ten  (10)  days  after  demand  therefor,  for  (i)  any  Indemnified  Taxes  attributable  to
such Noteholder (but only to the extent that the Issuer has not already indemnified the Administrative Agent for
such Indemnified Taxes and without limiting the obligation of the Issuer to do so), (ii) any Taxes attributable to
such  Noteholder’s  failure  to  comply  with  the  provisions  of  Section  14.05(g)  relating  to  the  maintenance  of  a
Participant Register, and (iii) any Excluded Taxes attributable to such Noteholder, in each case, that are payable or
paid by (or withheld from payments to) the Administrative Agent in connection with any Notes Documents, and
any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or
legally  imposed  or  asserted  by  the  relevant  Governmental  Authority.  A  certificate  as  to  the  amount  of  such
payment or liability delivered to any Noteholder by the Administrative Agent shall be conclusive absent manifest
error. Each Noteholder hereby authorizes the Administrative Agent to set off and apply any and all amounts at any
time owing to such Noteholder under any Notes Documents or otherwise payable by the Administrative Agent to
the Noteholder from any other source against any amount due to the Administrative Agent under this clause (e).

(f)

Status of Successors and Assignees.

(i)

Any Noteholder that is a successor or assignee of Perceptive Credit Holdings III, LP and
that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any
Notes Document shall deliver to the Issuer and the Administrative Agent at the time or times reasonably requested
by  the  Issuer  or  the  Administrative  Agent,  such  properly  completed  and  executed  documentation  reasonably
requested by the Issuer or the Administrative Agent as will permit such payments to be made without withholding
or  at  a  reduced  rate  of  withholding.  Notwithstanding  anything  to  the  contrary  in  the  preceding  sentence,  the
completion,  execution  and  submission  of  such  documentation  (other  than  such  documentation  set  forth  in
Section 5.03(f)(ii)) shall not be required if in such Noteholder’s reasonable judgment such completion, execution
or submission would subject such Noteholder to any material unreimbursed cost or expense or could materially
prejudice  the  legal  or  commercial  position  of  such  Noteholder.  For  the  avoidance  of  doubt,  notwithstanding
anything to the contrary in this Agreement, Perceptive Credit Holdings III, LP shall not be obligated to take any
actions that would disclose the identity of its partners.

(ii)

If a payment made to any Noteholder under any Notes Documents would be subject to U.S.
federal  withholding  Tax  imposed  by  FATCA  if  such  Noteholder  were  to  fail  to  comply  with  the  applicable
reporting  requirements  of  FATCA  (including  those  contained  in  Section  1471(b)  or  1472(b)  of  the  Code,  as
applicable),  such  Noteholder  shall  deliver  to  the  Issuer  and  the  Administrative  Agent  at  the  time  or  times
prescribed by Law and at such time or times

49

reasonably requested by the Issuer or the Administrative Agent such documentation prescribed by applicable Law
(including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably
requested  by  the  Issuer  or  the  Administrative  Agent  as  may  be  necessary  for  the  Issuer  and  the  Administrative
Agent to comply with their obligations under FATCA and to determine that such Noteholder has complied with
such Noteholder’s obligations under FATCA or to determine the amount, if any, to deduct and withhold from such
payment. Solely for purposes of this clause (ii), “FATCA” shall include any amendments made to FATCA after
the date of this Agreement.

Each  Recipient  agrees  that  if  any  form  or  certification  it  previously  delivered  expires  or  becomes  obsolete  or
inaccurate  in  any  respect,  it  shall  update  such  form  or  certification  or  promptly  notify  the  Issuer  and  the
Administrative Agent in writing of its legal inability to do so.

(g)

Treatment  of  Certain  Tax  Benefits.  If  any  party  to  this  Agreement  determines,  in  its  sole
discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified
pursuant to this Section 5.03 (including by the payment of additional amounts pursuant to this Section 5.03),  it
shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments
made  under  this  Section  5.03  with  respect  to  the  Taxes  giving  rise  to  such  refund),  net  of  all  out-of-pocket
expenses  (including  Taxes)  of  such  indemnified  party  and  without  interest  (other  than  any  interest  paid  by  the
relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such
indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 5.03 (plus
any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such
indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to
the contrary in this Section 5.03(g), in no event will the indemnified party be required to pay any amount to an
indemnifying party pursuant to this Section 5.03(g) the payment of which would place the indemnified party in a
less  favorable  net  after-Tax  position  than  the  indemnified  party  would  have  been  in  if  Tax  subject  to
indemnification  and  giving  rise  to  such  refund  had  not  been  deducted,  withheld  or  otherwise  imposed  and  the
indemnification  payments  or  additional  amounts  with  respect  to  such  Tax  had  never  been  paid.  This
Section 5.03(g) shall not be construed to require any indemnified party to make available its Tax returns (or any
other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(h) Mitigation  Obligations.  If  the  Issuer  is  required  to  pay  any  Indemnified  Taxes  or  additional
amounts  to  any  Noteholder  or  to  any  Governmental  Authority  for  the  account  of  any  Noteholder  pursuant  to
Section  5.01,  then  such  Noteholder  shall  (at  the  request  of  the  Issuer)  use  reasonable  efforts  to  designate  a
different office for subscribing for or booking its participation in the Notes hereunder or to assign and delegate its
rights and obligations hereunder to another of its offices, branches or Affiliates if, in the sole, reasonable judgment
of such Noteholder, such designation or assignment and delegation would (i) eliminate or reduce amounts payable
pursuant to Section 5.01, as the case may be, in the future, (ii) not subject such Noteholder to any unreimbursed
cost or expense and (iii) not otherwise be disadvantageous to such Noteholder. The Issuer hereby agrees to pay all
reasonable costs and expenses incurred by any Noteholder in connection with any such designation or assignment
and delegation.

(i)

United Kingdom Requirements.

50

(i)

Subject to sub-paragraph (ii) below, a UK Treaty Noteholder (or a Noteholder which would
be a UK Treaty Noteholder upon the completion of any necessary procedural formalities) and each Withholding
Agent which makes a payment to which that Noteholder is entitled shall co-operate in completing any procedural
formalities necessary for that Withholding Agent to obtain authorization to make that payment without a UK Tax
Deduction.

(ii)

Each  UK  Treaty  Noteholder  (or  a  Noteholder  which  would  be  a  UK  Treaty  Noteholder
upon  the  completion  of  any  necessary  procedural  formalities):  (A)  which  is  a  Noteholder  as  at  the  date  of  this
Agreement and that holds a passport under the UK DTTP Scheme, and which wishes that scheme to apply to this
Agreement, shall confirm its UK DTTP Scheme reference number and its jurisdiction of tax residence opposite its
name on Schedule 1; and (B) that becomes a Noteholder after the date of this Agreement and that holds a passport
under  the  UK  DTTP  Scheme,  and  which  wishes  that  scheme  apply  to  such  Noteholder’s  participation  in  this
Agreement,  shall  confirm  its  UK  DTTP  Scheme  reference  number  and  its  jurisdiction  of  tax  residence  in  the
documentation which it executes on becoming a party hereto as a Noteholder, and in each case under (A) and (B)
above, having done so, that Noteholder shall be under no further obligation pursuant to sub-paragraph (i) above.

(iii)

If a Noteholder has confirmed its UK DTTP Scheme reference number and its jurisdiction

of tax residence in accordance with sub-paragraph (i)(ii) above and:

in respect of that Noteholder; or

(A)

the Issuer making a payment to that Noteholder has not made an Issuer DTTP Filing

(B)

the Issuer making a payment to that Noteholder has made an Issuer DTTP Filing in
respect of that Noteholder but (1) that Issuer DTTP Filing has been rejected by HMRC, (2) HMRC has not given
the Issuer authority to make payments to that Noteholder without a UK Tax Deduction within 60 days of the date
of the Issuer DTTP Filing, or (3) HMRC has given authority for the Issuer to make payments to that Noteholder
without a UK Tax Deduction but such authority has subsequently been revoked, suspended or expired,

and in each case, the Issuer has notified that Noteholder in writing, then the applicable Noteholder
shall  co-operate  with  the  Issuer  in  completing  any  additional  procedural  formalities  necessary  for  that  Issuer  to
obtain authorization to make that payment without a UK Tax Deduction.

(iv)

If a Noteholder has not confirmed its UK DTTP Scheme reference number and jurisdiction
of tax residence in accordance with sub-paragraph (i)(ii) above, no Withholding Agent shall make an Issuer DTTP
Filing or file any other form relating to the UK DTTP Scheme in respect of a Commitment by such Noteholder or
its participation in any advance unless the Noteholder otherwise agrees.

(v)

The Issuer shall, promptly on making any Issuer DTTP Filing, deliver a copy of that Issuer

DTTP Filing to the Administrative Agent for delivery to the relevant Noteholder.

51

(vi)

A UK Non-Bank Noteholder shall promptly notify the Administrative Agent if there is any

change in the position from that set out in the applicable UK Tax Confirmation.

(vii)

If  the  Administrative  Agent  receives  a  UK  Tax  Confirmation  from  a  UK  Non-Bank

Noteholder it shall promptly provide a copy of such UK Tax Confirmation to the Issuer.

(viii) The Issuer shall upon becoming aware that the Issuer must make a UK Tax Deduction (or
that  there  is  any  change  in  the  rate  or  the  basis  of  a  UK  Tax  Deduction)  notify  the  Administrative  Agent
accordingly. Similarly, a Noteholder shall notify the Administrative Agent on becoming aware that a Withholding
Agent  must  make  a  UK  Tax  Deduction  (or  that  there  is  any  change  in  the  rate  or  the  basis  of  a  UK  Tax
Deduction). If the Administrative Agent receives such notification from a Noteholder, it shall promptly notify the
Issuer.

(j)

Noteholder Status Confirmation.

(i)

Each Noteholder which becomes a party after the date of this Agreement shall indicate in
the documentation which it executes on becoming a party which of the following categories it falls into: (A) not a
UK Qualifying Noteholder; (B) a UK Qualifying Noteholder (other than a UK Treaty Noteholder); or (C) a UK
Treaty  Noteholder  (or  a  Noteholder  which  would  be  a  UK  Treaty  Noteholder  upon  the  completion  of  any
necessary procedural formalities).

(ii)

If  a  Noteholder  fails  to  indicate  its  status  in  respect  of  the  Issuer  in  accordance  with
paragraph  (j)(i)  above,  then  such  Noteholder  shall  be  treated  for  the  purposes  of  this  Agreement  (including  by
each  Withholding  Agent)  as  if  it  is  not  a  UK  Qualifying  Noteholder  until  such  time  as  it  notifies  the
Administrative  Agent  which  categories  apply  (and  the  Administrative  Agent,  upon  receipt  of  such  notification,
shall promptly inform the Issuer). For the avoidance of doubt, the documentation which a Noteholder executes on
becoming a Party as a Noteholder shall not be invalidated by any failure of such Noteholder to comply with this
clause 5.03(j).

(iii) Where a Noteholder will become be a UK Treaty Noteholder only upon the completion of
certain  procedural  formalities,  it  shall  be  treated  for  the  purposes  of  this  Agreement  (including  by  each
Withholding  Agent)  as  if  it  is  not  a  UK  Qualifying  Noteholder  until  such  time  as  it  notifies  the  Administrative
Agent  that  such  procedural  formalities  are  complete  (and  the  Administrative  Agent,  upon  receipt  of  such
notification, shall promptly inform the Issuer).

(k)

VAT.

(i)

All  amounts  expressed  to  be  payable  under  any  Notes  Documents  by  any  party  to  any
Secured Party which (in whole or in part) constitute the consideration for a supply or supplies for VAT purposes
shall  be  deemed  to  be  exclusive  of  any  VAT  which  is  chargeable  on  such  supply  or  supplies,  and  accordingly,
subject to paragraph (ii) below, if VAT is or becomes chargeable on any supply made by any Secured Party to any
party under any Notes Documents and:

that party shall pay to the Secured Party (in addition to and at the same time

(A)

such Secured Party is required to account to the relevant tax authority for the VAT,

52

as paying any other consideration for such supply) an amount equal to the amount of such VAT (and such Secured
Party shall promptly provide an appropriate VAT invoice to such party); or

(B)

if such party is required to directly account for such VAT under the reverse charge
procedure provided for by article 44 of the Council Directive 2006/112/EC, or section 7A of the Value Added Tax
Act 1994 of the United Kingdom, in each case, as amended, or any relevant VAT provisions of the jurisdiction in
which such party received such supply, then such party shall account for the VAT at the appropriate rate (and the
relevant Secured Party must promptly provide an appropriate VAT invoice to such party stating that the amount is
charged in respect of a supply that is subject to VAT but that the reverse charge procedure applies).

(ii)

If  VAT  is  or  becomes  chargeable  on  any  supply  made  by  any  Secured  Party  (the  “VAT
Supplier”) to any other Secured Party (the “VAT Recipient”)  under  any  Notes  Documents,  and  any  party  other
than the VAT Recipient (the “Relevant Party”) is required by the terms of any Notes Documents to pay an amount
equal  to  the  consideration  for  that  supply  to  the  VAT  Supplier  (rather  than  being  required  to  reimburse  or
indemnify the VAT Recipient in respect of that consideration):

(iii)

where the VAT Supplier is the person required to account to the relevant tax authority for
the  VAT,  the  Relevant  Party  must  also  pay  to  the  VAT  Supplier  (at  the  same  time  as  paying  that  amount)  an
additional amount equal to the amount of VAT. The VAT Recipient must (where this sub-paragraph (ii)(A) applies)
promptly pay to the Relevant Party an amount equal to any credit or repayment the VAT Recipient receives from
the relevant tax authority which the VAT Recipient reasonably determines relates to the VAT chargeable on that
supply; and

(iv)

where the VAT Recipient is the person required to account to the relevant tax authority for
the VAT, the Relevant Party must promptly, following demand from the VAT Recipient, pay to the VAT Recipient
an amount equal to the VAT chargeable on that supply but only to the extent that the VAT Recipient reasonably
determines that it is not entitled to credit or repayment from the relevant tax authority in respect of that VAT.

(v) Where any Notes Documents require any party to reimburse or indemnify a Secured Party
for any cost or expense in connection with such Notes Documents, the reimbursement or indemnity (as the case
may be) shall be for the full amount of such cost or expense, including such part thereof as represents VAT, save to
the  extent  that  such  Secured  Party  reasonably  determines  that  it  is  entitled  to  credit  or  repayment  in  respect  of
such VAT from the relevant tax authority.

(vi)

Any  reference  in  this  clause  5.03(k)  to  any  party  shall,  at  any  time  when  such  party  is
treated as a member of a group or unity (or fiscal unity) for VAT purposes, include (where appropriate and unless
the context otherwise requires) a reference to the representative member of such group at such time as making the
supply, or (as appropriate) receiving the supply, under the grouping rules (as provided for in Article 11 of Council
Directive  2006/112/EC  (or  as  implemented  by  the  relevant  member  state  of  the  European  Union)  or  any  other
similar  provision  in  any  jurisdiction  which  is  not  a  member  state  of  the  European  Union,  including,  for  the
avoidance of doubt, in accordance with section 43 of the UK Value Added Tax Act 1994) so that a reference to a
party shall be construed as a reference to that party or the relevant group or unity (or fiscal

53

unity)  of  which  that  party  is  a  member  for  VAT  purposes  at  the  relevant  time  or  the  relevant  representative
member (or head) of that group or unity (or fiscal unity) at the relevant time (as the case may be).

(vii)

In relation to any supply made by a Secured Party to any party under a Notes Document, if
reasonably requested by such Secured Party, that party must as promptly as reasonably practicable provide such
Secured Party with details of that party’s VAT registration and such other information as is reasonably requested in
connection with such Secured Party’s VAT reporting requirements in relation to such supply.

(l)

Hybrid Mismatch Rules. Each Noteholder agrees to use commercially reasonable efforts to assist
the Issuer in preparing an analysis of available interest deductions to the Issuer under the UK hybrid mismatch
rules  contained  in  Part  6A  of  the  Taxation  (International  and  Other  Provisions)  Act  2010  at  Issuer’s  cost;
provided,  however,  that  notwithstanding  anything  to  the  contrary  in  this  Agreement,  no  Noteholder  shall  be
obligated to take any actions that would disclose the identity of its partners.

(m)

Survival.  Each  party’s  obligations  under  this  Section  5.03  shall  survive  the  resignation  or
replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Noteholder, the
termination of the Commitments and the repayment, satisfaction or discharge of all Obligations under any Notes
Documents.

in, all such real and personal assets and property, whether tangible or intangible, material to its respective business

Subsidiaries,  as  the  case  may  be,  to  utilize  such  assets  and  properties  in  the  ordinary  course  of  business  as
currently conducted and anticipated to be conducted.

(b)

Intellectual Property.

(i)

Schedule  7.05(b)  contains,  with  respect  to  the  Obligors  and  their  respective  Material
Intellectual  Property  (set  forth  on  an  Obligor-by-Obligor  basis  and  designated  as  to  whether  such  Material
Intellectual Property is owned or in-licensed):

(or any license or other Contract related thereto) and, to the knowledge of the Issuer, such license is legal, valid,
binding, enforceable, and in full force and effect. No Obligor is in material breach or default of any such license
and,  to  the  knowledge  of  the  Issuer,  no  third  party  (including  the  licensor  of  any  such  licensed  Material
Intellectual Property) is in material breach or default of any such license that, in either case, could reasonably be
expected to give rise to a right of rescission, termination, revision or amendment of any of any such license.

(iii) With respect to any  such  Material  Intellectual  Property  listed  on Schedule 7.05(b)  that  is
designated as being owned by the Obligors, each Obligor, as the case may be, is the beneficial owner of all right,
title and interest in and to such Person’s Material Intellectual Property that it owns, with no breaks in chain of title
and  with  good  and  marketable  title,  free  and  clear  of  any  Liens  or  Claims  of  any  kind  whatsoever  (other  than
Permitted Liens), and the Issuer or the applicable Obligor, as the case may be, has the right to use such Material

agreements  or  arrangements  relating  to  any  such  Material  Intellectual  Property,  including  any  development,
submission, services, research, license or support agreements, which bind, obligate or otherwise restrict the Issuer
or any of its Subsidiaries with respect to any such Material Intellectual Property in any material respect;

(C)

the  use  by  the  Issuer  or  any  of  its  Subsidiaries  of  any  such  Material  Intellectual
Property in the ordinary course of such Person’s businesses does not breach, violate, infringe or interfere with or
constitute a misappropriation of any valid rights arising under any Intellectual Property of any other Person that,
individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect;

(D)

(1) there are no pending or, to the Issuer’s knowledge, threatened in writing Claims
against the Issuer or any of its Subsidiaries asserted by any other Person relating to any such Material Intellectual
Property,  including  any  Claims  of  adverse  ownership,  invalidity,  infringement,  misappropriation,  violation  or

misappropriation  of,  or  otherwise  interfere  with,  or  otherwise  offer  a  license  with  respect  to  any  Intellectual
Property of any such other Person; and

(E)

to the Issuer’s knowledge, no such Material Intellectual Property is being infringed,
violated, misappropriated or otherwise used by any other Person without the express authorization of the Issuer;
and,  without  limiting  the  foregoing,  neither  the  Issuer  nor  any  of  its  Subsidiaries  has  put  any  other  Person  on
notice of actual or potential infringement, violation or misappropriation of any such Material Intellectual Property,
and neither the Issuer nor any of its Subsidiaries has initiated the enforcement of any Claim with respect to any

representations and warranties in Section 7.05(b)(iii):

(A)

each of the issued claims in such Patents is valid and enforceable;

(B)

each inventor named in such Patents has executed written Contracts with the Issuer
or one of its Subsidiaries (or a predecessor-in-interest) that properly and irrevocably assigns to the Issuer or such

claimed in such Patents;

claimed in any such Patent, have been dedicated to the public;

patent offices during prosecution of such Patents;

(D)

subsequent to the issuance of such Patents, none of the Issuer, any of its Subsidiaries
or  any  of  their  respective  predecessors-in-interest,  has  filed  any  disclaimer  or  made  or  permitted  any  other
voluntary reduction in the scope of the Inventions claimed in such Patents;

(E)

(F)

no subject matter designated allowable or allowed by the U.S. Patent and Trademark

any patent applications or patents of any third party and have not been the subject of any interference, and such
Patents  are  not  and  have  not  been  the  subject  of  any  re-examination,  opposition  or  any  other  post-grant
proceedings,  and  neither  the  Issuer  nor  any  of  its  Subsidiaries  has  knowledge  of  any  basis  for  any  such
interference,  re-examination,  opposition,  inter  partes  review,  post  grant  review,  or  any  other  post-grant
proceedings;

(G)

representatives, have engaged in any conduct, or omitted to perform any necessary act, the result of which would
invalidate or render unpatentable or unenforceable any such Patent; and

all maintenance fees, annuities, and the like due or payable on or with respect to any
such Patents have been timely paid or the failure to so pay could not, individually or in the aggregate, reasonably
be expected to result in a Material Adverse Change.

such  projected  financial  information  is  not  to  be  viewed  as  facts,  and  that  no  assurances  can  be  given  that  any
particular  projections  will  be  realized  and  that  actual  results  during  the  period  or  periods  covered  by  any  such
projections  may  differ  from  the  projected  results  and  such  differences  may  be  material).  In  respect  of  the
Certificates  of  Title,  the  information  supplied  by  or  on  behalf  of  the  Obligors  to  the  lawyers  who  prepared  any

The Issuer hereby acknowledges that the Administrative Agent or the Noteholders may not wish to receive
material non-public information with respect to the Issuer or its Affiliates, or the respective securities of any of the
foregoing,  and  the  Administrative  Agent,  the  Noteholders  or  their  respective  personnel  may  be  engaged  in

material  non-public  information,  the  parties  hereto  covenant  and  agree  that,  as  except  for  any  notice  required
pursuant  to  clause  (a)  above,  Issuer  will  not  become  obligated  to  provide  the  Administrative  Agent,  any

imposed upon it or upon its properties or assets prior to the date on which penalties attach thereto, and all lawful
Claims for labor, materials and supplies which, if unpaid, might become a Lien upon any properties or assets of

levies, or such claims are being contested in good faith by appropriate proceedings and are adequately reserved
against in accordance with GAAP, and (ii) all other lawful Claims which, if unpaid, would by Law become a Lien
upon any properties or assets of the Issuer or any of its Subsidiaries, other than any Permitted Lien.

8.05

of the Collateral shall provide that they shall not be terminated or cancelled without at least thirty (30) days’ (ten

notice  of  cancellation  or  modification  of  any  such  insurance  policies  or  reduction  of  coverage  or  amounts
thereunder shall entitle any Secured Party to renew any such policies, cause the coverage and amounts thereof to

documented costs and expenses of all such inspections.

Indebtedness (including, for the avoidance of doubt, the case where there is no Bond Hedge Transaction relating
to  such  Permitted  Convertible  Indebtedness),  the  payment  of  such  excess  cash  shall  not  be  permitted  by  the
preceding sentence.

any  principal  not  so  declared  to  be  due  and  payable  may  thereafter  be  declared  to  be  due  and  payable),  and
thereupon the principal of the Notes so declared to be due and payable, together with accrued interest thereon and
all fees and other Obligations, shall become due and payable immediately (in the case of the Notes, at the Early
Redemption  Price  therefor),  without  presentment,  demand,  protest  or  other  notice  of  any  kind,  all  of  which  are
hereby waived by each Obligor; and in case of an Event of Default described in Section 11.01(h), the principal of
the  Notes  then  outstanding,  together  with  accrued  interest  thereon  and  all  fees  and  other  Obligations,  shall
automatically  become  due  and  payable  immediately  (in  the  case  of  the  Notes,  at  the  Early  Redemption  Price
therefor),  without  presentment,  demand,  protest  or  other  notice  of  any  kind,  all  of  which  are  hereby  waived  by
each Obligor.

Agreement to be remedied (including without limitation by paying any unpaid amount thereunder) and otherwise
exercise any and all rights of the Issuer or such Subsidiary, as the case may be, thereunder, as may be necessary to
prevent  or  cure  any  default.  Without  limiting  the  foregoing,  upon  any  such  default,  the  Issuer  and  each  of  its
Subsidiaries  shall  promptly  execute,  acknowledge  and  deliver  to  the  Administrative  Agent  such  instruments  as
may  reasonably  be  required  of  the  Issuer  or  such  Subsidiary  to  permit  the  Administrative  Agent  and  the
Noteholders to cure any default under the applicable Material Agreement or permit the Administrative Agent and
the Noteholders to take such other action required to enable the Administrative Agent and the Noteholders to cure
or  remedy  the  matter  in  default  and  preserve  the  interests  of  the  Administrative  Agent  or  Noteholders.  Any
amounts  paid  by  the  Administrative  Agent  or  Noteholders  pursuant  to  this  Section  11.04  shall  be  payable  on

Noteholders), and is hereby authorized, to (i) act as the disbursing and collecting agent for the Noteholders with
respect  to  all  payments  and  collections  arising  in  connection  with  the  Notes  Documents  (including  in  any
proceeding  described  in  Section 11.01(h) or  any  other  bankruptcy,  insolvency  or  similar  proceeding);  provided
that (i) the Administrative Agent shall only be required to act in such agency capacity if it has notified the Issuer
and the Noteholders in writing that it has elected to do so, and (ii) so long as the Administrative Agent has not
delivered any such election notice it shall not be deemed to be acting as a disbursing and collecting agent for any
other Noteholder or Secured Party and no Person (including any Withholding Agent) shall be authorized to make
any  payment  to  the  Administrative  Agent  for  such  purpose,  (ii)  file  and  prove  claims  and  file  other  documents
necessary or desirable to allow the claims of the Secured Parties with respect to any Obligation in any proceeding
described in Section 11.01(h) or any other bankruptcy, insolvency or similar proceeding (but not to vote, consent
or otherwise act on behalf of such Secured Party), (iii) act as collateral agent for each Secured Party for purposes
of  the  perfection  of  all  Liens  created  by  such  agreements  and  all  other  purposes  stated  therein,  (iv)  manage,
supervise and otherwise deal with the Collateral, (v) take such other action as is necessary or desirable to maintain
the perfection and priority of the Liens created or purported to be created by the Notes Documents, (vi) except as
may be otherwise specified in any Notes Document, exercise all remedies given to the Administrative Agent and
the other Secured Parties with respect to the Collateral, whether under the Notes Documents, applicable Laws or
otherwise  and  (vii)  execute  any  amendment,  consent  or  waiver  under  the  Notes  Documents  on  behalf  of  any
Noteholder that has consented in writing to such amendment, consent or waiver; provided that the Administrative
Agent hereby appoints, authorizes and directs each Noteholder to act as collateral sub-agent for the Administrative
Agent and the Noteholders for purposes of the perfection of all Liens with respect to the Collateral, including any
deposit account maintained by any Obligor with, and cash and Permitted Cash Equivalent Investments held by,
such  Noteholder,  and  may  further  authorize  and  direct  the  Noteholders  to  take  further  actions  as  collateral  sub-
agents  for  purposes  of  enforcing  such  Liens  or  otherwise  to  transfer  the  Collateral  subject  thereto  to  the
Administrative Agent, and each Noteholder hereby agrees to take such further actions to the extent, and only to
the extent, so authorized and directed.

(c)

Limited Duties.  The  Noteholders  and  the  Obligors  hereby  each  acknowledge  and  agree  that  the
Administrative Agent (i) has undertaken its role hereunder purely as an accommodation to the parties hereto and
the Transactions, (ii) is receiving no compensation for undertaking such role and (iii) subject only to the notice
provisions  set  forth  in  Section  12.09,  may  resign  from  such  role  at  any  time  for  any  reason  or  no  reason
whatsoever. Without limiting the foregoing, the parties hereto further acknowledge and agree that under the Notes
Documents, the Administrative Agent (i) is acting solely on behalf of the Noteholders (except to the limited extent
provided in Section 12.11), with duties that are entirely administrative in nature and do not (and are not intended
to) create any fiduciary obligations, notwithstanding the use of the defined term “the Administrative Agent”, the
terms “agent”, “administrative agent” and “collateral agent” and similar terms in any Notes Document to refer to
the Administrative Agent, which terms are used for title purposes only, (ii) is not assuming any obligation under
any Notes Document other than as expressly set forth therein or any role as agent, fiduciary or trustee of or for any
Noteholder  or  any  other  Secured  Party  and  (iii)  shall  have  no  implied  functions,  responsibilities,  duties,
obligations or other liabilities under any Notes Document (fiduciary or otherwise), and each

97

Noteholder hereby waives and agrees not to assert any claim against the Administrative Agent based on the roles,
duties and legal relationships expressly disclaimed in this clause (c).

12.02 Binding Effect. Each Noteholder agrees that (i) any action taken by the Administrative Agent or the
Majority Noteholders (or, if expressly required hereby, a greater proportion of the Noteholders) in accordance
with the provisions of the Notes Documents, (ii) any action taken by the Administrative Agent in reliance upon
the instructions of the Majority Noteholders (or, where so required, such greater proportion) and (iii) the exercise
by the Administrative Agent or the Majority Noteholders (or, where so required, such greater proportion) of the
powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be
authorized and binding upon all of the Secured Parties.

12.03 Use of Discretion.

(a)

No Action without Instructions. The Administrative Agent shall not be required to exercise any
discretion  or  take,  or  to  omit  to  take,  any  action,  including  with  respect  to  enforcement  or  collection,  except
(subject to clause (b) below) any action it is required to take or omit to take (i) under any Notes Document or (ii)
pursuant  to  instructions  from  the  Majority  Noteholders  (or,  where  expressly  required  by  the  terms  of  this
Agreement, a greater proportion of the Noteholders).

(b)

Right Not to Follow Certain Instructions. Notwithstanding Section 12.03(a) or any other term or
provision of this Section 12, the Administrative Agent shall not be required to take, or to omit to take, any action
(i)  unless,  upon  demand,  the  Administrative  Agent  receives  an  indemnification  satisfactory  to  it  from  the
Noteholders  (or,  to  the  extent  applicable  and  acceptable  to  the  Administrative  Agent,  any  other  Secured  Party)
against  all  liabilities  that,  by  reason  of  such  action  or  omission,  may  be  imposed  on,  incurred  by  or  asserted
against the Administrative Agent or any Related Parties thereof or (ii) that is, in the opinion of the Administrative
Agent, in its sole and absolute discretion, contrary to any Notes Document, applicable Law or the best interests of
the Administrative Agent or any of its Affiliates or Related Parties.

12.04 Delegation of Rights and Duties. The Administrative Agent may, upon any term or condition it specifies,
delegate or exercise any of its rights, powers and remedies under, and delegate or perform any of its duties or any
other action with respect to, any Notes Document by or through any trustee, co-agent, employee, attorney-in-fact
and  any other Person  (including  any  Secured  Party).  Any  such  Person  shall  benefit from this Section 12  to  the
extent provided by the Administrative Agent.

12.05 Reliance and Liability.

(a)

The Administrative Agent may, without incurring any liability hereunder, (i) consult with any of its
Related  Parties  and,  whether  or  not  selected  by  it,  any  other  advisors,  accountants  and  other  experts  (including
advisors to, and accountants and experts engaged by, any Obligor) and (ii) rely and act upon any document and
information and any telephone message or conversation, in each case believed by it to be genuine and transmitted,
signed or otherwise authenticated by the appropriate parties.

98

(b)

Neither the Administrative Agent nor any of its Related Parties shall be liable for any action taken
or omitted to be taken by any of them under or in connection with any Notes Document, and each Noteholder and
the Issuer hereby waives and shall not assert (and the Issuer shall cause each other Obligor to waive and agree not
to assert) any right, claim or cause of action based thereon, except to the extent of liabilities resulting primarily
from the fraudulent conduct or behavior of the Administrative Agent or, as the case may be, such Related Party
(each  as  determined  in  a  final,  non-appealable  judgment  or  order  by  a  court  of  competent  jurisdiction)  in
connection with the duties expressly set forth herein. Without limiting the foregoing, the Administrative Agent:

(i)

shall  not  be  responsible  or  otherwise  incur  liability  for  any  action  or  omission  taken  in
reliance upon the instructions of the Majority Noteholders or for the actions or omissions of any of their Related
Parties selected with reasonable care (other than employees, officers and directors of the Administrative Agent,
when acting on behalf of the Administrative Agent);

(ii)

shall  not  be  responsible  to  any  Secured  Party  for  the  due  execution,  legality,  validity,
enforceability, effectiveness, genuineness, sufficiency or value of, or the attachment, perfection or priority of any
Lien created or purported to be created under or in connection with, any Notes Document;

(iii) makes no warranty or representation, and shall not be responsible, to any Secured Party for
any  statement,  document,  information,  representation  or  warranty  made  or  furnished  by  or  on  behalf  of  any
Related Party, in or in connection with any Notes Document or any transaction contemplated therein, whether or
not transmitted by the Administrative Agent, including as to completeness, accuracy, scope or adequacy thereof,
or for the scope, nature or results of any due diligence performed by the Administrative Agent in connection with
the Notes Documents; and

(iv)

shall not have any duty to ascertain or to inquire as to the performance or observance of any
provision of any Notes Document, whether any condition set forth in any Notes Document is satisfied or waived,
as  to  the  financial  condition  of  any  Obligor  or  as  to  the  existence  or  continuation  or  possible  occurrence  or
continuation  of  any  Default  or  Event  of  Default  and  shall  not  be  deemed  to  have  notice  or  knowledge  of  such
occurrence or continuation unless it has received a notice from the Issuer, any Noteholder describing such Default
or  Event  of  Default  clearly  labeled  “notice  of  default”  (in  which  case  the  Administrative  Agent  shall  promptly
give notice of such receipt to all Noteholders);

and, for each of the items set forth in clauses (i) through (iv) above, each Noteholder and the Issuer hereby waives
and agrees not to assert (and the Issuer shall cause each other Obligor to waive and agree not to assert) any right,
claim or cause of action it might have against the Administrative Agent based thereon.

12.06 Administrative  Agent  Individually.  The  Administrative  Agent  and  its  Affiliates  may  make  loans  and
other  extensions  of  credit  to,  acquire  Equity  Interests  of,  engage  in  any  kind  of  business  with,  any  Obligor  or
Affiliate thereof as though it were not acting as the Administrative Agent and may receive separate fees and other
payments therefor. To the extent the Administrative

99

Agent or any of its Affiliates subscribes for or purchases any Notes or otherwise becomes a Noteholder hereunder,
it shall have and may exercise the same rights and powers hereunder and shall be subject to the same obligations
and liabilities as any other Noteholder and the terms “Noteholder”, “Majority Noteholder”, and any similar terms
shall,  except  where  otherwise  expressly  provided  in  any  Notes  Document,  include,  without  limitation,  the
Administrative Agent or such Affiliate, as the case may be, in its individual capacity as Noteholder or as one of
the Majority Noteholders, respectively.

12.07 Noteholder  Credit  Decision.  Each  Noteholder  acknowledges  that  it  has,  independently  and  without
reliance  upon  the  Administrative  Agent,  any  Noteholder  or  any  of  their  Related  Parties  or  upon  any  document
solely or in part because such document was transmitted by the Administrative Agent or any of its Related Parties,
conducted its own independent investigation of the financial condition and affairs of each Obligor and has made
and  continues  to  make  its  own  credit  decisions  in  connection  with  entering  into,  and  taking  or  not  taking  any
action  under,  any  Notes  Document  or  with  respect  to  any  transaction  contemplated  in  any  Notes  Document,  in
each case based on such documents and information as it shall deem appropriate.

12.08 Expenses; Indemnities.

(a)

Each Noteholder agrees to reimburse the Administrative Agent and each of its Related Parties (to
the extent not reimbursed by any Obligor) promptly upon demand for such Noteholder’s Proportionate Share of
any costs and expenses (including fees, charges and disbursements of financial, legal and other advisors and Other
Taxes paid in the name of, or on behalf of, any Obligor) that may be incurred by the Administrative Agent or any
of  its  Related  Parties  in  connection  with  the  preparation,  syndication,  execution,  delivery,  administration,
modification, consent, waiver or enforcement (whether through negotiations, through any work-out, bankruptcy,
restructuring  or  other  legal  or  other  proceeding  or  otherwise)  of,  or  legal  advice  in  respect  of  its  rights  or
responsibilities under, any Notes Document.

(b)

Each  Noteholder  further  agrees  to  indemnify  the  Administrative  Agent  and  each  of  its  Related
Parties (to the extent not reimbursed by any Obligor), from and against such Noteholder’s aggregate Proportionate
Share  of  the  liabilities  (including  taxes,  interests  and  penalties  imposed  for  not  properly  withholding  or  backup
withholding on payments made to on or for the account of any Noteholder) that may be imposed on, incurred by
or asserted against the Administrative Agent or any of its Related Parties in any matter relating to or arising out
of,  in  connection  with  or  as  a  result  of  any  Notes  Document  or  any  other  act,  event  or  transaction  related,
contemplated  in  or  attendant  to  any  such  Notes  Document,  or,  in  each  case,  any  action  taken  or  omitted  to  be
taken  by  the  Administrative  Agent  or  any  of  its  Related  Parties  under  or  with  respect  to  any  of  the  foregoing;
provided that no Noteholder shall be liable to the Administrative Agent or any of its Related Parties to the extent
such liability has resulted primarily from the gross negligence or willful misconduct of the Administrative Agent
or,  as  the  case  may  be,  such  Related  Party,  as  determined  by  a  court  of  competent  jurisdiction  in  a  final  non-
appealable judgment or order.

12.09 Resignation of the Administrative Agent.

100

(a)

At  any  time  upon  not  less  than  five  (5)  Business  Days  prior  written  notice,  the  Administrative
Agent  may  resign  as  the  “the  Administrative  Agent”  hereunder,  in  whole  or  in  part  (in  the  sole  and  absolute
discretion of the Administrative Agent), effective on the date set forth in such notice, which effective date shall
not be less than five (5) (or more than thirty (30)) days following delivery of such notice. If the Administrative
Agent  delivers  any  such  notice,  the  Majority  Noteholders  shall  have  the  right  to  appoint  a  successor  (which
successor shall not be a Disqualified Institution) to the Administrative Agent; provided that if a successor to the
Administrative  Agent  has  not  been  appointed  on  or  before  the  effectiveness  of  the  resignation  of  the  resigning
Administrative  Agent,  then  the  resigning  Administrative  Agent  may,  on  behalf  of  the  Noteholders,  appoint  any
Person  reasonably  chosen  by  it  (other  than  a  Disqualified  Institution)  as  the  successor  to  the  Administrative
Agent.

(b)

Effective  immediately  upon  its  resignation,  (i)  the  resigning  Administrative  Agent  shall  be
discharged  from  its  duties  and  obligations  under  the  Notes  Documents  to  the  extent  set  forth  in  the  applicable
resignation  notice,  (ii)  the  Noteholders  shall  assume  and  perform  all  of  the  duties  of  the  Administrative  Agent
until a successor the Administrative Agent shall have accepted a valid appointment hereunder, (iii) the resigning
Administrative  Agent  and  its  Related  Parties  shall  no  longer  have  the  benefit  of  any  provision  of  any  Notes
Document  other  than  with  respect  to  (x)  any  actions  taken  or  omitted  to  be  taken  while  such  resigning
Administrative  Agent  was,  or  because  the  Administrative  Agent  had  been,  validly  acting  as  the  Administrative
Agent under the Notes Documents or (y) any continuing duties such resigning Administrative Agent continues to
perform,  and  (iv)  subject  to  its  rights  under  Section  12.04,  the  resigning  Administrative  Agent  shall  take  such
action  as  may  be  reasonably  necessary  to  assign  to  the  successor  the  Administrative  Agent  its  rights  as  the
Administrative  Agent  under  the  Notes  Documents.  Effective  immediately  upon  its  acceptance  of  a  valid
appointment  as  the  Administrative  Agent,  a  successor  the  Administrative  Agent  shall  succeed  to,  and  become
vested with, all the rights, powers, privileges and duties of the resigning Administrative Agent under the Notes
Documents.

12.10 Release of Collateral or Guarantees. Each Noteholder hereby consents to the release and hereby directs
the Administrative Agent to release (or, in the case of Section 12.10(b)(ii), release or subordinate) the following:

(a)

any Subsidiary of the Issuer from its guaranty of any Obligation of any Obligor if all of the Equity
Interests  in  such  Subsidiary  owned  by  any  Obligor  or  any  of  its  Subsidiaries  are  disposed  of  in  an  Asset  Sale
permitted under the Notes Documents (including pursuant to a waiver or consent), to the extent that, after giving
effect to such Asset Sale, such Subsidiary would not be required to guaranty any Obligations pursuant to Section
8.12(a); and

(b)

any  Lien  held  by  the  Administrative  Agent  for  the  benefit  of  the  Secured  Parties  against  (i)  any
Collateral  that  is  disposed  of  by  an  Obligor  or  any  of  its  Subsidiaries  in  an  Asset  Sale  permitted  by  the  Notes
Documents  (including  pursuant  to  a  valid  waiver  or  consent),  (ii)  any  property  subject  to  a  Lien  described  in
Section  9.02(c)  and  (iii)  all  of  the  Collateral  and  all  Obligors,  upon  (w)  termination  of  the  Commitments,  (x)
payment and satisfaction in full of the Notes and all other Obligations (other than (i) for the Warrant Obligations
and (y) contingent obligations as to which no Claims have been asserted) that the Administrative Agent has been
notified  in  writing  are  then  due  and  payable,  (y)  deposit  of  cash  collateral  with  respect  to  all  contingent
Obligations, in amounts and on terms and conditions and with parties satisfactory to

101

the Administrative Agent and each Indemnified Party that is owed such Obligations and (z) to the extent requested
by the Administrative Agent, receipt by the Secured Parties of liability releases from the Obligors each in form
and substance acceptable to the Administrative Agent.

Each  Noteholder  hereby  directs  the  Administrative  Agent,  and  the  Administrative  Agent  hereby  agrees,  upon
receipt of reasonable advance notice from the Issuer, to execute and deliver or file such documents and to perform
other actions reasonably necessary to release the guarantees and Liens when and as directed in this Section 12.10.

12.11 Additional Secured Parties. The benefit of the provisions of the Notes Documents directly relating to the
Collateral  or  any  Lien  granted  thereunder  shall  extend  to  and  be  available  to  any  Secured  Party  that  is  not  a
Noteholder so long as, by accepting such benefits, such Secured Party agrees, as among the Administrative Agent
and all other Secured Parties, that such Secured Party is bound by (and, if requested by the Administrative Agent,
shall  confirm  such  agreement  in  a  writing  in  form  and  substance  acceptable  to  the  Administrative  Agent)  this
Section 12  and  the  decisions  and  actions  of  the  Administrative  Agent  and  the  Majority  Noteholders  (or,  where
expressly required by the terms of this Agreement, a greater proportion of the Noteholders) to the same extent a
Noteholder  is  bound;  provided  that,  notwithstanding  the  foregoing,  (i)  such  Secured  Party  shall  be  bound  by
Section  12.08  only  to  the  extent  of  liabilities,  costs  and  expenses  with  respect  to  or  otherwise  relating  to  the
Collateral  held  for  the  benefit  of  such  Secured  Party,  in  which  case  the  obligations  of  such  Secured  Party
thereunder  shall  not  be  limited  by  any  concept  of  Proportionate  Share  or  similar  concept,  (ii)  each  of  the
Administrative  Agent  and  each  Noteholder  shall  be  entitled  to  act  at  its  sole  discretion,  without  regard  to  the
interest  of  such  Secured  Party,  regardless  of  whether  any  Obligation  to  such  Secured  Party  thereafter  remains
outstanding,  is  deprived  of  the  benefit  of  the  Collateral,  becomes  unsecured  or  is  otherwise  affected  or  put  in
jeopardy  thereby,  and  without  any  duty  or  liability  to  such  Secured  Party  or  any  such  Obligation  and  (iii)  such
Secured Party shall not have any right to be notified of, consent to, direct, require or be heard with respect to, any
action taken or omitted in respect of the Collateral or under any Notes Document.

SECTION 13
GUARANTEE

13.01 The Guarantee. The Subsidiary Guarantors hereby jointly and severally guarantee to the Administrative
Agent and the Noteholders, and their successors and assigns, the prompt payment in full when due (whether at
stated  maturity,  by  acceleration  or  otherwise)  of  the  principal  of  and  interest  on  the  Notes,  all  fees  and  other
amounts and Obligations from time to time owing to the Administrative Agent and the Noteholders by the Issuer
and each other Obligor under this Agreement or under any other Notes Document (other than in the case of the
Irish Subsidiary Guarantor, the Warrant Certificate), in each case strictly in accordance with the terms hereof and
thereof  (such  obligations  being  herein  collectively  called  the  “Guaranteed  Obligations”).  The  Subsidiary
Guarantors hereby further jointly and severally agree that if the Issuer or any other Obligor shall fail to pay in full
when  due  (whether  at  stated  maturity,  by  acceleration  or  otherwise)  any  of  the  Guaranteed  Obligations,  the
Subsidiary Guarantors shall promptly pay the same, without any demand or notice whatsoever, and that in the case
of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same shall be promptly
paid in full when due

102

(whether  at  extended  maturity,  by  acceleration  or  otherwise)  in  accordance  with  the  terms  of  such  extension  or
renewal.

13.02 Obligations  Unconditional.  The  obligations  of  the  Subsidiary  Guarantors  under  Section  13.01  are
absolute  and  unconditional,  joint  and  several,  irrespective  of  the  value,  genuineness,  validity,  regularity  or
enforceability  of  the  obligations  of  the  Issuer  or  any  other  Subsidiary  Guarantor  under  this  Agreement  or  any
other agreement or instrument referred to herein, or any substitution, release or exchange of any other guarantee
of or security for any of the Guaranteed Obligations, and, to the fullest extent permitted by all applicable Laws,
irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or
defense  of  a  surety  or  guarantor,  it  being  the  intent  of  this  Section 13.02  that  the  obligations  of  the  Subsidiary
Guarantors  hereunder  shall  be  absolute  and  unconditional,  joint  and  several,  under  any  and  all  circumstances.
Without  limiting  the  generality  of  the  foregoing,  it  is  agreed  that  the  occurrence  of  any  one  or  more  of  the
following  shall  not  alter  or  impair  the  liability  of  the  Subsidiary  Guarantors  hereunder,  which  shall  remain
absolute and unconditional as described above:

(a)

at  any  time  or  from  time  to  time,  without  notice  to  the  Subsidiary  Guarantors,  the  time  for  any
performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or
compliance shall be waived;

(b)

any  of  the  acts  mentioned  in  any  of  the  provisions  of  this  Agreement  or  any  other  agreement  or

instrument referred to herein shall be done or omitted;

(c)

the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed
Obligations shall be modified, supplemented or amended in any respect, or any right under this Agreement or any
other agreement or instrument referred to herein shall be waived or any other guarantee of any of the Guaranteed
Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with; or

(d)

any lien or security interest granted to, or in favor of, the Secured Parties as security for any of the

Guaranteed Obligations shall fail to be perfected.

The  Subsidiary  Guarantors  hereby  expressly  waive  diligence,  presentment,  demand  of  payment,  protest
and  all  notices  whatsoever,  and  any  requirement  that  the  Administrative  Agent  or  any  Noteholder  exhaust  any
right, power or remedy or proceed against the Issuer or any other Subsidiary Guarantor under this Agreement or
any other agreement or instrument referred to herein, or against any other Person under any other guarantee of, or
security for, any of the Guaranteed Obligations.

13.03 Reinstatement. The obligations of the Subsidiary Guarantors under this Section 13 shall be automatically
reinstated  if  and  to  the  extent  that  for  any  reason  any  payment  by  or  on  behalf  of  the  Issuer  in  respect  of  the
Guaranteed  Obligations  is  rescinded  or  must  be  otherwise  restored  by  any  holder  of  any  of  the  Guaranteed
Obligations,  whether  as  a  result  of  any  proceedings  in  bankruptcy  or  reorganization  or  otherwise,  and  the
Subsidiary Guarantors jointly and severally agree that they shall indemnify the Secured Parties on demand for all
reasonable costs and expenses (including reasonable and documented fees of counsel) properly incurred by such

103

Persons in connection with such rescission or restoration, including any such costs and expenses properly incurred
in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar
payment under any bankruptcy, insolvency or similar law.

13.04 Subrogation.  The  Subsidiary  Guarantors  hereby  jointly  and  severally  agree  that,  until  the  payment  and
satisfaction in full in cash of all Guaranteed Obligations (other than contingent obligations for which no Claim has
been asserted) and the expiration and termination of the Commitments, they shall not exercise any right or remedy
arising  by  reason  of  any  performance  by  them  of  their  guarantee  in  Section  13.01,  whether  by  subrogation  or
otherwise, against the Issuer or any other guarantor of any of the Guaranteed Obligations or any security for any
of the Guaranteed Obligations.

13.05 Remedies.  The  Subsidiary  Guarantors  jointly  and  severally  agree  that,  as  between  the  Subsidiary
Guarantors, on one hand, and the Administrative Agent and the Noteholders, on the other hand, the obligations of
the Issuer under this Agreement and under the other Notes Documents may be declared to be forthwith due and
payable  as  provided  in  Section 11  (and  shall  be  deemed  to  have  become  automatically  due  and  payable  in  the
circumstances provided in Section 11) for purposes of Section 13.01 notwithstanding any stay, injunction or other
prohibition  preventing  such  declaration  (or  such  obligations  from  becoming  automatically  due  and  payable)  as
against  the  Issuer  and  that,  in  the  event  of  such  declaration  (or  such  obligations  being  deemed  to  have  become
automatically due and payable), such obligations (whether or not due and payable by the Issuer) shall forthwith
become due and payable by the Subsidiary Guarantors for purposes of Section 13.01.

13.06 Instrument  for  the  Payment  of  Money.  Each  Subsidiary  Guarantor  hereby  acknowledges  that  the
guarantee in this Section 13 constitutes an instrument for the payment of money, and consents and agrees that the
Administrative  Agent  and  the  Noteholders,  at  their  sole  option,  in  the  event  of  a  dispute  by  such  Subsidiary
Guarantor in the payment of any moneys due hereunder, shall have the right to proceed by motion for summary
judgment in lieu of complaint pursuant to N.Y. Civ. Prac. L&R § 3213.

13.07 Continuing Guarantee. The guarantee in this Section 13 is a continuing guarantee, and shall apply to all
Guaranteed Obligations whenever arising.

(a) 

13.08 General  Limitation  on  Guarantee  Obligations. 
In  any  action  or  proceeding  involving  any
provincial, territorial or state corporate Law, or any state or federal bankruptcy, insolvency, reorganization or other
Law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under Section 13.01
would otherwise be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any
other  creditors,  on  account  of  the  amount  of  its  liability  under  Section  13.01,  then,  notwithstanding  any  other
provision hereof to the contrary, the amount of such liability shall, without any further action by such Subsidiary
Guarantor, the Administrative Agent, any Noteholder or any other Person, be automatically limited and reduced to
the  highest  amount  that  is  valid  and  enforceable  and  not  subordinated  to  the  claims  of  other  creditors  as
determined in such action or proceeding; and (b) notwithstanding anything to the contrary in this Agreement, the
obligations, liabilities and undertakings under this Agreement (including in the guarantee in this section 13) shall
not be

104

deemed to be undertaken or incurred by an Irish Subsidiary Guarantor to the extent that the same would constitute
unlawful financial assistance prohibited by Section 82 of the Irish Companies Act (or any analogous provision of
any other applicable Law).

SECTION 14
MISCELLANEOUS

14.01 No Waiver. No failure on the part of the Administrative Agent or the Noteholders to exercise and no delay
in exercising, and no course of dealing with respect to, any right, power or privilege under any Notes Document
shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any
Notes Document preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. The remedies provided herein are cumulative and not exclusive of any remedies provided by Law.

Exculpation, Indemnification, etc.

(i)

In no event shall any party hereto, any successor, transferee or assignee of any party hereto,
or  any  of  their  respective  Affiliates,  directors,  officers,  employees,  attorneys,  agents,  advisors  or  controlling
parties (each, an “Exculpated Party”) have any obligation or responsibility for (and the Obligors and the Secured
Parties, as applicable, jointly and severally waive any claims they may have in respect of) any Loss, on any theory
of  liability,  for  consequential,  indirect,  special  or  punitive  damages  arising  out  of  or  otherwise  relating  to  this
Agreement or any of the other Notes Document or any of the Transactions or the actual or proposed use of the
proceeds of the Notes; provided that, nothing in this clause (i)  shall  relieve  any  Obligor  of  any  obligation  such
Obligor  may  have  to  indemnify  an  Indemnified  Party,  as  provided  in  clause  (ii)  below,  against  any  special,
indirect, consequential or punitive damages asserted against such Indemnified Party by a third party. Each party
hereto agrees, to the fullest extent permitted by applicable Law, that it will not assert, directly or indirectly, any
Claim against any Exculpated Party with respect to any of the foregoing.

(c)

Each Obligor, jointly and severally, hereby indemnifies the Administrative Agent, each Noteholder,
each  of  their  respective  permitted  successors,  transferees  and  assigns  and  each  of  their  respective  Affiliates,
directors, officers, employees, attorneys, agents, advisors and controlling parties (each, an “Indemnified Party”)
from and against, and agrees to hold them harmless against, any and all Claims and Losses of any kind (including
reasonable fees and disbursements of counsel), joint or several, that may be incurred by or asserted or awarded
against any Indemnified Party, in each case arising out of or in connection with or relating to any investigation,
litigation or proceeding (each, a “Proceeding”) or the preparation of any defense with respect thereto arising out

Person, or an Indemnified Party is otherwise a party thereto, and whether or not any of the conditions precedent
set  forth  in  Section 6  are  satisfied  or  the  other  transactions  contemplated  by  this  Agreement  are  consummated,
except  to  the  extent  such  Claim  or  Loss  is  found  in  a  final,  non-appealable  judgment  by  a  court  of  competent
jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. No Obligor
shall assert any Claim against any Indemnified Party, on any theory of liability, for consequential, indirect, special

without the consent of such affected Noteholder;

106

(b)

the consent of all of the Noteholders shall be required to:

(i)

amend,  modify,  discharge,  terminate  or  waive  any  of  the  terms  of  this  Agreement  or  any

Agent and the Issuer shall be permitted to amend such provision, and, in each case, such amendment shall become
effective  without  any  further  action  or  consent  of  any  other  party  to  any  Notes  Document  if  the  same  is  not
objected  to  in  writing  by  the  Majority  Noteholders  to  the  Administrative  Agent  within  ten  (10)  Business  Days
following receipt of notice thereof.

14.05 Successors and Assigns.

(a)

General. The provisions of this Agreement and the other Notes Documents shall be binding upon
and shall inure to the benefit of the parties hereto or thereto and their respective successors and assigns permitted
hereby  or  thereby,  except  that  no  Obligor  may  assign  or  otherwise  transfer  any  of  its  rights  or  obligations
hereunder without the prior written consent of the Administrative Agent. Any Noteholder may assign or otherwise
transfer any of its rights or obligations hereunder or under any of the other Notes Documents (i) to an assignee in
accordance with the provisions of Section 14.05(b), (ii) by way of participation in accordance with the provisions
of Section 14.05(e),  or  (iii)  by  way  of  pledge  or  assignment  of  a  security  interest  subject  to  the  restrictions  of

(other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent
provided in Section 14.05(f) and, to the extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent and the Noteholders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

107

(b)

Assignments by Noteholder. Any Noteholder may at any time transfer or assign to one or more
Eligible Transferees (or, if an Event of Default has occurred and is continuing, to any Person) all or a portion of its
rights and obligations under this Agreement (including all or a portion of the Notes at the time owing to it) and the
other Notes Documents; provided that (i) no such assignment shall be made to any Obligor, any Affiliate of any
Obligor, or any employees or directors of any Obligor at any time, (ii) no such assignment shall be made without
the prior written consent of the Administrative Agent, and (iii) so long as no Event of Default shall have occurred
and is continuing, no such assignment shall be made without the prior written consent of the Issuer (such consents
not  to  be  unreasonably  withheld,  delayed  or  conditioned)  to  a  Disqualified  Institution;  provided  that  the  Issuer
shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the
Administrative Agent within five (5) Business Days after having received notice thereof. Subject to the recording
thereof  by  the  Noteholder  pursuant  to  Section  14.05(d),  from  and  after  the  effective  date  specified  in  each
Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the
interest assigned by such Assignment and Assumption, have the rights and obligations of such Noteholder under
this Agreement and the other Notes Document, and correspondingly the assigning Noteholder shall, to the extent
of  the  interest  assigned  by  such  Assignment  and  Assumption,  be  released  from  its  obligations  under  this
Agreement  (and,  in  the  case  of  a  transfer  or  assignment  covering  all  of  the  Noteholder’s  rights  and  obligations
under this Agreement, such Noteholder shall cease to be a party hereto) and the other Notes Documents but shall
continue  to  be  entitled  to  the  benefits  of  Section  5  and  Section  14.03.  Any  assignment  or  transfer  by  the
Noteholder of rights or obligations under this Agreement that does not comply with this Section 14.05(b) shall be
treated  for  purposes  of  this  Agreement  as  a  sale  by  such  Noteholder  of  a  participation  in  such  rights  and
obligations in accordance with Section 14.05(e).

(c)

Amendments to Notes Document. Each of the Administrative Agent, the Noteholders, the Issuer
and its Subsidiaries agrees to enter into such amendments to the Notes Documents, and such additional Security
Documents and other instruments and agreements, in each case in form and substance reasonably acceptable to
the  Administrative  Agent,  the  Noteholders  the  Issuer  and  its  Subsidiaries,  as  shall  reasonably  be  necessary  to
implement and give effect to any assignment made under this Section 14.05.

(d)

Notes Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent
of the Issuer, shall maintain at one of its offices in the United States a copy of each Assignment and Assumption
delivered  to  it  and  a  register  for  the  recordation  of  the  names  and  addresses  of  the  Noteholders,  and  the
Commitments of, and principal amounts (and stated interest) of the Notes owing to, each Noteholder pursuant to
the terms hereof from time to time (the “Notes Register”). The entries in the Register shall be conclusive absent
manifest error, and the Issuer, the Administrative Agent and the Noteholders shall treat each Person whose name
is  recorded  in  the  Register  pursuant  to  the  terms  hereof  as  a  Noteholder  hereunder  for  all  purposes  of  this
Agreement.  The  Register  shall  be  available  for  inspection  by  the  Issuer  and  any  Noteholder,  at  any  reasonable
time and from time to time upon reasonable prior notice.

(e)

Participations. Any Noteholder may at any time, without the consent of, or notice to, the Issuer,
sell participations to any Person (other than a Disqualified Institution (so long as no Event of Default shall have
occurred  and  is  continuing),  natural  person  or  any  Obligor  or  any  of  its  Subsidiaries  or  Affiliates)  (each,  a
“Participant”) in all or a portion of the Noteholder’s rights

108

and/or obligations under this Agreement (including all or a portion of the Commitment and/or the Notes owing to
it);  provided  that  (i)  such  Noteholder’s  obligations  under  this  Agreement  shall  remain  unchanged,  (ii)  such
Noteholder shall remain solely responsible to the other parties hereto for the performance of such obligations and
(iii)  the  Issuer  shall  continue  to  deal  solely  and  directly  with  such  Noteholder  in  connection  therewith.  Any
agreement  or  instrument  pursuant  to  which  any  Noteholder  sells  such  a  participation  shall  provide  that  such
Noteholder  shall  retain  the  sole  right  to  enforce  the  Notes  Documents  and  to  approve  any  amendment,
modification or waiver of any provision of the Notes Documents; provided that such agreement or instrument may
provide  that  such  Noteholder  shall  not,  without  the  consent  of  the  Participant,  agree  to  any  amendment,
modification or waiver that would (i) increase or extend the term of such Noteholder’s Commitment, (ii) extend
the date fixed for the payment of principal of or interest on the Notes or any portion of any fee hereunder payable
to  the  Participant,  (iii)  reduce  the  amount  of  any  such  payment  of  principal,  or  (iv)  reduce  the  rate  at  which
interest  is  payable  thereon  to  a  level  below  the  rate  at  which  the  Participant  is  entitled  to  receive  such  interest.
Subject to Section 14.05(f), the Issuer agrees that each Participant shall be entitled to the benefits of Section 5
(subject  to  the  requirements  and  limitations  therein  including  the  requirements  under  Section  5.03(f)  (it  being
understood  that  the  documentation  required  under  Section  5.03(f)  shall  be  delivered  to  the  participating
Noteholder)) to the same extent as if it were a Noteholder and had acquired its interest by assignment pursuant to
Section 14.05(b); provided that such Participant agrees to be subject to the provisions of Section 5.03(h) as if it
were an assignee under Section 14.05(b) above. To the extent permitted by applicable Law, each Participant also
shall be entitled to the benefits of Section 4.03(a) as though it were a Noteholder.

(f)

Limitations on Rights of Participants. A Participant shall not be entitled to receive any greater
payment under Sections 5.01 or 5.03 than such Noteholder would have been entitled to receive with respect to the
participation  sold  to  such  Participant,  except  to  the  extent  such  entitlement  to  receive  a  greater  payment  results
from a Change in Law that occurs after the Participant acquired the applicable participation.

(g)

Participant  Register.  Each  Noteholder  that  sells  a  participation  shall,  acting  solely  for  this
purpose as a non-fiduciary agent of the Issuer, maintain a register on which it enters the name and address of each
Participant  and  the  principal  amounts  (and  stated  interest)  of  each  Participant’s  interest  in  the  Notes  or  other
Obligations under the Notes Documents (the “Participant Register”); provided that no Noteholder shall have any
obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any
information  relating  to  a  Participant’s  interest  in  any  Commitments,  Notes,  or  its  other  Obligations  under  any
Notes  Document)  to  any  Person  except  to  the  extent  that  such  disclosure  is  necessary  to  establish  that  such
Commitment,  Note,  or  other  Obligation  is  in  registered  form  under  Section  5f.103-1(c)  of  the  United  States
Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such
Noteholder  shall  treat  each  Person  whose  name  is  recorded  in  the  Participant  Register  as  the  owner  of  such
participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of
doubt,  the  Administrative  Agent  (in  its  capacity  as  Administrative  Agent)  shall  have  no  responsibility  for
maintaining a Participant Register.

(h)

Certain Pledges. Any Noteholder may at any time pledge or assign a security interest in all or any

portion of its rights under the Notes Documents to secure obligations of such

109

Noteholder, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no
such pledge or assignment shall release such Noteholder from any of its obligations hereunder or substitute any
such pledgee or assignee for such Noteholder as a party hereto.

14.06 Survival. The obligations of the Issuer under Sections 5.01, 5.02, 5.03, 14.03, 14.05, 14.06, 14.09, 14.10,
14.11, 14.12, 14.13, 14.14 and the obligations of the Subsidiary Guarantors under Section 13 (solely to the extent
guaranteeing any of the obligations under the foregoing Sections) shall survive the repayment of the Obligations
and the termination of the Commitment and, in the case of the Noteholders’ assignment of any interest in the
Commitment or the Notes hereunder, shall survive, in the case of any event or circumstance that occurred prior to
the effective date of such assignment, the making of such assignment, notwithstanding that the Noteholders may
cease to be “Noteholders” hereunder. In addition, each representation and warranty made, or deemed to be made
by a Notes Subscription Request, herein or pursuant hereto shall survive the making of such representation and
warranty.

may take concurrent proceedings in any number of jurisdictions.

(b)

Alternative  Process.  Nothing  herein  shall  in  any  way  be  deemed  to  limit  the  ability  of  the
Administrative  Agent  and  the  Noteholders  to  serve  any  process  or  summons  in  any  manner  permitted  by  any
applicable Law.

(c) Waiver of Venue, Etc. Each Obligor irrevocably waives to the fullest extent permitted by law any
objection that it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out

such suit, action or proceeding shall be conclusive and may be enforced in any court to the jurisdiction of which
the Issuer is or may be subject, by suit upon judgment.

or  other  Governmental  Authority  or  as  may  otherwise  be  required  pursuant  to  any  applicable  Law,  (vi)  if
requested  or  required  to  do  so  in  connection  with  any  litigation  or  similar  proceeding;  provided  that,  unless
otherwise prohibited by applicable Law, court order or decree, the Administrative Agent and each Noteholder, as
applicable, shall provide prior notice to the Obligor to allow such Obligor an opportunity to obtain a protective
order,  (vii)  that  has  been  publicly  disclosed  (other  than  as  a  result  of  a  disclosure  in  violation  of  this  Section

remedy  permitted  hereunder  or  under  any  other  Notes  Document,  (x)  on  a  confidential  basis  to  (A)  any  rating

Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers of other market
identifiers with respect to the Notes or (xi) to any other party hereto.

14.17 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate
applicable to any Notes, together with all fees, charges and other amounts that are treated as interest on such Notes
under  applicable  Law  (collectively,  “charges”),  shall  exceed  the  maximum  lawful  rate  (the  “Maximum  Rate”)
that may be contracted for, charged, taken, received or reserved by the Administrative Agent and the Noteholder
holding such Notes in accordance

112

with  applicable  Law,  the  rate  of  interest  payable  in  respect  of  such  Notes  hereunder,  together  with  all  charges
payable in respect thereof, shall be limited to the Maximum Rate. To the extent lawful, the interest and charges
that would have been paid in respect of such Notes but were not paid as a result of the operation of this Section
shall be cumulated and the interest and charges payable to such Noteholder in respect of other Notes or periods
shall  be  increased  (but  not  above  the  amount  collectible  at  the  Maximum  Rate  therefor)  until  such  cumulated
amount, together with interest thereon at the Federal Funds Effective Rate for each day to the date of repayment,
shall  have  been  received  by  such  Noteholder.  Any  amount  collected  by  such  Noteholder  that  exceeds  the
maximum amount collectible at the Maximum Rate shall be applied to the reduction of the principal balance of
such Notes so that at no time shall the interest and charges paid or payable in respect of such Notes exceed the
maximum amount collectible at the Maximum Rate.

14.18 Early  Redemption  Fee.  The  parties  hereto  acknowledge  and  agree  that,  to  the  extent  the  Early
Redemption Fee is applicable to any repurchase, repayment or redemption of principal of any Notes at any time,
such Early Redemption Fee is not intended to be a penalty assessed as a result of any such repurchase, repayment
or redemption of the Notes, but rather is the product of a good faith, arm’s length commercial negotiation between
the Issuer and the Noteholders relating to the mutually satisfactory compensation payable to the Noteholders by
the Issuer in respect of the Notes made hereunder. In furtherance of the foregoing, to the fullest extent permitted
by applicable Law, the Obligors hereby jointly and severally waive any rights or Claims any of them may have
under any such applicable Law (whether or not in effect on the Closing Date) that would prohibit or restrict the
payment  of  the  Early  Redemption  Fee  under  any  of  the  circumstances  provided  herein  or  in  any  other  Notes
Document, including payment after acceleration of the Notes.

14.19 Judgment Currency.

(a)

If,  for  the  purposes  of  obtaining  judgment  in  any  court,  it  is  necessary  to  convert  a  sum  due
hereunder in Dollars into another currency, the parties hereto agree, to the fullest extent permitted by Law, that the
rate of exchange used shall be that at which, in accordance with normal banking procedures, the Administrative
Agent  could  purchase  Dollars  with  such  other  currency  at  the  buying  spot  rate  of  exchange  in  the  New  York
foreign exchange market on the Business Day immediately preceding that on which any such judgment, or any
relevant part thereof, is given.

(b)

The obligations of the Obligors in respect of any sum due to the Administrative Agent hereunder
and under the other Notes Documents shall, notwithstanding any judgment in a currency other than Dollars, be
discharged only to the extent that on the Business Day following receipt by the Administrative Agent of any sum
adjudged to be so due in such other currency the Administrative Agent may, in accordance with normal banking
procedures, purchase Dollars with such other currency. If the amount of Dollars so purchased is less than the sum
originally due to the Administrative Agent in Dollars, the Issuer agrees, to the fullest extent that it may effectively
do  so,  as  a  separate  obligation  and  notwithstanding  any  such  judgment,  to  indemnify  the  Administrative  Agent
against  such  loss.  If  the  amount  of  Dollars  so  purchased  exceeds  the  sum  originally  due  to  the  Administrative
Agent in Dollars, the Administrative Agent shall remit such excess to the Issuer.

113

14.20 USA  PATRIOT  Act.  The  Administrative  Agent  and  the  Noteholders  hereby  notify  the  Obligors  that
pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26,
2001)) (the “Patriot Act”), they are required to obtain, verify and record information that identifies the Obligors,
which  information  includes  the  name  and  address  of  each  Obligor  and  other  information  that  will  allow  such
Person to identify such Obligor in accordance with the Patriot Act.

14.21 Acknowledgement  and  Consent  to  Bail-In  of  Affected  Financial  Institutions.  Notwithstanding
anything to the contrary in any Notes Document or in any other agreement, arrangement or understanding among
any  such parties, each  party  hereto  acknowledges  that  any  liability  of  any  Affected Financial Institution arising
under  any  Notes  Document,  to  the  extent  such  liability  is  unsecured,  may  be  subject  to  the  Write-Down  and
Conversion  Powers  of  the  applicable  Resolution  Authority  and  agrees  and  consents  to,  and  acknowledges  and
agrees to be bound by:

(a)

the application of any Write-Down and Conversion Powers by the applicable Resolution Authority
to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial
Institution; and

(b)

the effects of any Bail-In Action on any such liability, including, if applicable:

(i)

a reduction in full or in part or cancellation of any such liability;

(ii)

a  conversion  of  all,  or  a  portion  of,  such  liability  into  shares  or  other  instruments  of
ownership in such Affected Financial Institution, its parent undertaking, or a bridge institution that may be issued
to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in
lieu of any rights with respect to any such liability under this Agreement or any other Notes Document; or

(iii)

the  variation  of  the  terms  of  such  liability  in  connection  with  the  exercise  of  the  Write-

Down and Conversion Powers of the applicable Resolution Authority.

looking statements), which qualify these representations and warranties in their entirety:

4.1.

Organization, Good Standing and Qualification. The Company is duly incorporated, validly
existing and in good standing under the laws of the jurisdiction of its incorporation and has all requisite corporate
power and authority to carry on its business as now conducted and to own or lease its properties. The Company is
duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property makes such qualification or leasing necessary
unless the failure to so qualify has not had and could not reasonably be expected to have a Material Adverse
Effect. Each of the Company’s “Subsidiaries” (for purposes of this Agreement, as defined in Rule 405 under the

conducted and to own or lease its properties. Each of the Company’s Subsidiaries is duly qualified as a foreign
corporation, partnership or limited liability company, as applicable, to transact business and is in good standing in
each jurisdiction in which the conduct of its business or its ownership or leasing of property makes such
qualification or leasing necessary unless the failure to so qualify has not had and could not reasonably be expected
to have a Material Adverse Effect. All of the issued and outstanding capital stock or other equity or ownership
interests of each of the Company’s Subsidiaries have been duly authorized and validly issued, are fully paid and
nonassessable and are owned by the Company, directly or through Subsidiaries, free and clear of any security
interest, mortgage, pledge, lien, encumbrance or adverse claim.

4.2.

Authorization. The Company has the requisite corporate power and authority and has taken
all requisite corporate action necessary for, and no further action on the part of the Company, its officers, directors
and shareholders is necessary for, (i) the authorization, execution and delivery of this Agreement, (ii) the
authorization of the performance of all obligations of the Company hereunder, and (iii) the authorization, issuance
and delivery of the Shares. This Agreement constitutes the legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability, relating to or affecting creditors’
rights generally and to general equitable principles.

4.3.

Capitalization. The SEC Filings accurately reflect as of their respective dates (a) the

authorized shares of the Company; (b) the number of shares issued and outstanding; (c) the number of shares
issuable pursuant to the Company’s stock plans; and (d) the number of shares issuable and reserved for issuance
pursuant to securities (other than the Shares) exercisable for, or convertible into or exchangeable for any shares of
the Company. All of the issued and outstanding shares of the Company’s have been duly authorized and validly
issued and are fully paid, nonassessable and none of such shares were issued in violation of any pre-emptive rights
and such shares were issued in compliance in all material respects with applicable Cayman Islands, state and
federal securities law and any rights of third parties. Except as described in the SEC Filings, no Person is entitled
to pre-emptive or similar statutory or contractual rights with respect to the issuance by the Company of any
securities of the Company. Except as described in the SEC filings, there are no outstanding warrants, options,
convertible securities or other rights, agreements or arrangements of any character under which the Company is or
may be obligated to issue any equity securities of any kind and except as contemplated by this Agreement. Except
as described in the SEC filings, there are no voting agreements, buy-sell agreements, option or right of first
purchase agreements or other agreements of any kind among the Company and any of the securityholders of the
Company relating to the securities of the Company held by them. Except as described in the SEC filings, no
Person has the right to require the Company to register any securities of the Company under the 1933 Act,
whether on a demand basis or in connection with the registration of securities of the Company for its own account
or for the account of any other Person.

The issuance and sale of the Shares hereunder will not obligate the Company to issue Ordinary

Shares or other securities to any other Person (other than the Investor) and will

not result in the adjustment of the exercise, conversion, exchange or reset price of any outstanding security.

The Company does not have outstanding shareholder purchase rights or “poison pill” or any similar

arrangement in effect giving any Person the right to purchase any equity interest in the Company upon the
occurrence of certain events.

4.4.

Valid Issuance. The Shares have been duly and validly authorized and, when issued and
paid for pursuant to this Agreement, will be validly issued, fully paid and nonassessable, and shall be free and
clear of all encumbrances and restrictions (other than those created by the Investor), except for restrictions on
transfer set forth herein or imposed by applicable securities laws.

No Material Adverse Effect. Since June 30, 2022, (i) there has not been any event,

occurrence, development or condition of any character that has had or would reasonably be expected to have a

other property to its shareholders. No material event, liability, fact, circumstance, occurrence or development has
occurred or exists, or is reasonably expected to occur or exist, with respect to the Company or its Subsidiaries or
their respective businesses, properties, operations, assets or financial condition that would be required to be
disclosed by the Company under applicable Law that has not been publicly disclosed.

4.6.

material respects with applicable accounting requirements and the rules and regulations of the SEC with respect
thereto as in effect at the time of filing (or to the extent corrected by a subsequent restatement) and present fairly,
in all material respects, the financial position of the Company as of the dates shown and its results of operations
and cash flows for the periods shown, and such financial statements have been prepared in conformity with United
States generally accepted accounting principles applied on a consistent basis during the periods involved
(“GAAP”) (except as may be disclosed therein or in the notes thereto, except that the unaudited quarterly financial
statements may not contain all footnotes required by GAAP, as permitted by Form 10-Q under the 1934 Act).

4.7.

Consents. The execution, delivery and performance by the Company of the Transaction

Documents and the offer, issuance and sale of the Shares require no consent of, action by or in respect of, or filing
with, any Person, governmental body, agency, or official other than (a) filings that have been made pursuant to
applicable state securities laws, (b) post-sale filings pursuant to applicable state and federal securities laws and (c)
filings pursuant to the rules and regulations of Nasdaq, each of which the Company has filed or undertakes to file
within the applicable time. Subject to the accuracy of the representations and warranties of the Investor set forth in
Section 5 hereof, the Company has taken all action necessary to exempt (i) the issuance and sale of the Shares and
(ii) the other transactions contemplated by the

Transaction Documents from the provisions of any shareholder rights plan or other “poison pill” arrangement, any
anti-takeover, business combination or control share law or statute binding on the Company or to which the
Company or any of its assets and properties is subject that is or could reasonably be expected to become
applicable to the Investors as a result of the transactions contemplated hereby, including without limitation, the
issuance of the Shares and the ownership, disposition or voting of the Shares by the Investors or the exercise of
any right granted to the Investors pursuant to this Agreement or the other Transaction Documents.

4.8.

Legal Proceedings. Except as described in the SEC Filings or as previously disclosed to the

Investor, there are no legal, governmental or regulatory investigations, actions, suits or proceedings pending to
which the Company or any of its Subsidiaries is or may reasonably be expected to become a party or to which any
property of the Company is or may reasonably be expected to become the subject that, individually or in the
aggregate, if determined adversely to the Company or its Subsidiaries, could (i) reasonably be expected to have a
Material Adverse Effect or (ii) adversely affect or challenge the legality, validity or enforceability of the
Transaction Documents. Neither the Company nor any of its Subsidiaries, nor, to the Company’s Knowledge, any
director or officer thereof, is or has been the subject of any action involving a judicially filed claim of violation of
or liability under U.S. federal, state or foreign securities laws or a judicially filed claim of breach of fiduciary
duty. Except as described in the SEC Filings or as previously disclosed to the Investor, there has not been, and to
the Company’s Knowledge, there is not pending or threatened, any investigation by the SEC involving the
Company or any current or former director or officer of the Company. The SEC has not issued any stop order or
other order suspending the effectiveness of any registration statement filed by the Company or any of its
Subsidiaries under the 1933 Act or the 1934 Act.

4.9.

statements and other documents required to be filed by the Company under 1933 Act and the 1934 Act, including

made pursuant to the 1934 Act. The Company is engaged in all material respects only in the business described in
the SEC Filings and the SEC Filings contain a complete and accurate description in all material respects of the
business of the Company.

4.10. Compliance. The Company is not (i) in default under or in violation of (and no event has

occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the
Company under), nor has the Company received notice of a claim that it is in default under or that it is in violation
of, any indenture, loan or credit agreement or any other agreement or instrument to which it is a party or by which
it or any of its properties is bound (whether or not such default or violation has been waived), (ii) in violation of
any judgment, decree or order of any court, arbitrator or governmental body or (iii) in violation of any statute,
rule, ordinance or regulation of any governmental authority, including without limitation all foreign, federal, state

leases with which the Company and its Subsidiaries are in compliance and with no exceptions, except such as

4.14. No Conflict, Breach, Violation or Default. The execution, delivery and performance of the

Transaction Documents by the Company and the issuance and sale of the Shares in accordance with the provisions
thereof will not (i) conflict with or result in a breach or violation of (a) any of the terms and provisions of, or
constitute a default under, the Company’s Articles of Association, both as in effect on the date hereof (true and
complete copies of which have been made available to the Investor through the EDGAR system), or (b) assuming
the accuracy of the representations and warranties in Section 5, any applicable statute, rule, regulation or order of
any governmental agency or body or any court, domestic or foreign, having jurisdiction over the Company or its
Subsidiaries, or any of their assets or properties.

the Company’s Knowledge, there is no existing infringement by another Person of any of the Intellectual Property
Rights that would have or would reasonably be expected to have a Material Adverse Effect. The Company and its
Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of its
Intellectual Property Rights, except where failure to do so would not, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect. All material licenses or other material agreements under which the
Company is granted Intellectual Property Rights are in full force and effect and, to the Company’s knowledge,
there is no material default by any other party thereto, except as would not reasonably be expected to have a
Material Adverse Effect. The Company has no reason to believe that the licensors under such licenses and other
agreements do not have and did not have all requisite power and authority to grant the rights to the Intellectual
Property Rights purported to be granted thereby. The consummation of the transactions contemplated hereby and
by the other Transaction Documents will not result in the alteration, loss, impairment of or restriction on the
Company’s or any of its Subsidiaries’ ownership or right to use any Intellectual Property Rights that is material to
the conduct of the Company’s business as currently conducted.

4.16. Certificates, Authorities and Permits. The Company and its Subsidiaries possess adequate

certificates, authorities or permits issued by appropriate governmental agencies or bodies necessary to conduct the
business now operated by them, except where failure to so possess would not reasonably be expected to,
individually or in the aggregate, result in a Material Adverse Effect. The Company and its Subsidiaries have not
received any notice of proceedings relating to the revocation or modification of any such certificate, authority or
permit that, if determined adversely to the Company or its Subsidiaries, would reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect.

4.17. Environmental Matters. Except as would not reasonably be expected, individually or in the

aggregate, to have a Material Adverse Effect, neither the Company nor any of its Subsidiaries is in violation of
any statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or
foreign, relating to the use, disposal or release of hazardous or toxic substances or relating to the protection or
restoration of the environment or human exposure to hazardous or toxic substances (collectively, “Environmental
Laws”), has released any hazardous substances regulated by Environmental Law on to any real property that it
owns or operates, or has received any written notice or claim it is liable for any off-site disposal or contamination
pursuant to any Environmental Laws; and to the Company’s Knowledge, there is no pending or threatened
investigation that would reasonably be expected to lead to such a claim.

for, the delisting of the Ordinary Shares from Nasdaq.

Investor for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding
entered into by or on behalf of the Company.

4.20. No Directed Selling Efforts or General Solicitation. Neither the Company nor any of its

Subsidiaries nor any Person acting on its behalf has conducted any general solicitation or general advertising (as
those terms are used in Regulation D (“Regulation D”) promulgated under the 1933 Act) in connection with the
offer or sale of any of the Shares. The Company has offered the Shares for sale only to “accredited investors”
within the meaning of Rule 501 under the 1933 Act.

4.21. No Integrated Offering. Neither the Company nor any of its subsidiaries nor any Person

acting on its behalf has, directly or indirectly, made any offers or sales of any Company security or solicited any
offers to buy any Company security, under circumstances that would adversely affect reliance by the Company on
Section 4(a)(2) for the exemption from registration for the transactions contemplated hereby or would require
registration of the Shares under the 1933 Act.

4.22. Private Placement. Assuming the accuracy of the representations and warranties of the

Investor set forth in Section 5, the offer and sale of the Shares to the Investor as contemplated hereby is exempt
from the registration requirements of the 1933 Act. The issuance and sale of the shares does not contravene the
rules and regulations of Nasdaq.

4.23. No Unlawful Payments. Neither the Company nor any of its Subsidiaries nor any director,
officer, or employee of the Company or any of its Subsidiaries nor, to the knowledge of the Company, any agent,
affiliate or other person associated with or acting on behalf of the Company or any of its Subsidiaries has (i) used

political activity; (ii) made or taken an act in furtherance of an offer, promise or authorization of any direct or

made, offered, agreed, requested or taken an act in furtherance of any unlawful bribe or other unlawful benefit,
including, without limitation, any rebate, payoff, influence payment, kickback or other unlawful or improper
payment or benefit. The Company and its Subsidiaries have instituted, maintain and enforce, and will continue to
maintain and enforce policies and procedures designed to promote and ensure compliance with all applicable anti-
bribery and anti-corruption laws.

4.24. Compliance with Anti-Money Laundering Laws. The operations of the Company and its

Subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and
reporting requirements, including those of the Currency and Foreign Transactions Reporting Act of 1970, as
amended, the applicable money laundering

statutes of all jurisdictions where the Company or any of its Subsidiaries conducts business, the rules and
regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced
by any governmental or regulatory agency (collectively, the “Anti-Money Laundering Laws”) and no action, suit

involving the Company or any of its Subsidiaries with respect to the Anti-Money Laundering Laws is pending or,
to the knowledge of the Company, threatened.

4.25. No Conflicts with Sanctions Laws. Neither the Company nor any of its Subsidiaries,

associated with or acting on behalf of the Company or any of its Subsidiaries is currently the subject or the target
of any sanctions administered or enforced by the U.S. Government, (including, without limitation, the Office of

such proceeds to any subsidiary, joint venture partner or other person or entity (i) to fund or facilitate any
activities of or business with any person that, at the time of such funding or facilitation, is the subject or the target
of Sanctions, (ii) to fund or facilitate any activities of or business in any Sanctioned Country or (iii) in any other
manner that will result in a violation by any person (including any person participating in the transaction, whether
as underwriter, advisor, investor or otherwise) of Sanctions. For the past five years, the Company and its
Subsidiaries have not knowingly engaged in and are not now knowingly engaged in any dealings or transactions
with any person that at the time of the dealing or transaction is or was the subject or the target of Sanctions or with
any Sanctioned Country.

1933 Act. The Company shall be responsible for the fees of its Transfer Agent and all DTC fees associated with
such issuance.

7.9.

Subsequent Equity Sales. From the date hereof until six months after the Closing Date, the
Investor shall not, directly or indirectly, sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any
Ordinary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares or enter into
any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of Ordinary Shares.

7.10. Securities Laws. The Investor hereby acknowledges its obligations under the U.S. federal

securities laws, including with respect to the prohibition of any person in possession of “material non-public
information” about a company from purchasing or selling, directly or indirectly, securities of such company
(including entering into short selling or hedge transactions involving such securities), or from communicating
such information to any other person under circumstances in which it is reasonably foreseeable that such person is
likely to purchase or sell such securities.

7.11. Passive Foreign Investment Company; Controlled Foreign Corporation. Not later than

forty-five (45) days after the end of Company’s fiscal year, the Company will determine whether it and each of its
Subsidiaries constitutes a “passive foreign investment company” (a “PFIC”) or a “controlled foreign corporation”
(a “CFC”) as defined for U.S. tax purposes for such fiscal year and if Company determines it is a PFIC or CFC,
will so advise each Investor. For each fiscal year of the Company, commencing with the first fiscal year for which
it is determined to be a PFIC, the Company and each of its Subsidiaries shall no later than ninety (90) days after
the end of such fiscal year, furnish the Investor with all information necessary for it to make a qualified electing
fund (“QEF”) election, including (i) a PFIC Annual Information Statement under Section 1295(b) of the U.S.
Internal Revenue Code, as amended (the “Code”) and (ii) all information necessary for it to complete IRS Form
8621 (or a successor form). All information shall be provided in English. The Company will obtain the advice of
one of the “big four” accounting firms to make the determinations and provide the information and statements as
described in this paragraph.

8.

Survival and Indemnification.

8.1.

Survival. The representations, warranties, covenants and agreements contained in this

Agreement shall survive the Closing of the transactions contemplated by this Agreement for the applicable statute
of limitations.

8.2.

Indemnification. The Company agrees to indemnify and hold harmless the Investor and its

Affiliates and their respective directors, officers, trustees, members, managers, employees and agents, and their
respective successors and assigns, from and against any and all losses, claims, damages, liabilities and expenses,
including without limitation reasonable attorney fees and disbursements and other expenses reasonably incurred in
connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and
the costs of enforcement thereof (collectively, “Losses”), to which such Person may become subject as a result of
or relating to (a) any breach of representation, warranty, covenant or agreement made by or to be performed on the
part of the Company under this Agreement or (b) any action instituted against the Investor or its Affiliates by any
stockholder of the Company who is not an Affiliate of the Investor, with respect to any of the transactions
contemplated by this Agreement (unless such action is based upon a breach of the Investor’s representations,
warranties or covenants under this Agreement or any conduct by the Investor or its Affiliates which constitutes
fraud, gross negligence, willful misconduct or malfeasance), and will reimburse any such Person for all such
amounts as they are incurred by such Person.

8.3.

Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder

shall (i) give prompt notice to the indemnifying party of any claim

with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of
such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such
claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the
indemnifying party has agreed to pay such fees or expenses, (b) the indemnifying party shall have failed to
assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the
reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists
between such person and the indemnifying party with respect to such claims (in which case, if the person notifies
the indemnifying party in writing that such person elects to employ separate counsel at the expense of the
indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf
of such person); and provided, further, that the failure of any indemnified party to give notice as provided herein
shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give
notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is
understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be
liable for fees or expenses of more than one separate firm of attorneys at any time for such indemnified party. No
indemnifying party will, except with the consent of the indemnified party, which consent shall not be
unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement that
does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect of such claim or litigation. No indemnified party will, except with the
consent of the indemnifying party, consent to entry of any judgment or enter into any settlement. The indemnity
agreements contained herein shall be in addition to any cause of action or similar right of the Investor or its
Affiliates against the Company or others and any liabilities the Company may be subject to pursuant to law.

9.

Successors and Assigns. This Agreement may not be assigned by a party hereto without the

prior written consent of the Company or the Investor, as applicable, provided, however, that the Investor may
assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring

“Shares” shall be deemed to refer to the securities received by the Investors in connection with such transaction.

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability
without invalidating the remaining provisions hereof but shall be

interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable law, and
any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such
provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any
provision of law which renders any provision hereof prohibited or unenforceable in any respect.

9.9.

REGISTRATION RIGHTS AGREEMENT

This REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is made and entered into as of

November 9, 2022 by and among MeiraGTx Holdings plc, a Cayman Islands exempted company (the
“Company”), and Johnson & Johnson Innovation – JJDC, Inc. (the “Investor”) in connection with that certain
Securities Purchase Agreement by and among the Company and the Investor (the “Purchase Agreement”).
Capitalized terms used herein have the respective meanings ascribed thereto in the Purchase Agreement unless
otherwise defined herein.

Exhibit 10.40

The parties hereby agree as follows:

1.

Certain Definitions.

As used in this Agreement, the following terms shall have the following meanings:

“Investor” means the Investor identified above and any Affiliate or permitted transferee of the Investor

who is a subsequent holder of Registrable Securities.

“Confidential Treatment Request” means any confidential treatment request submitted to the Securities

and Exchange Commission (the “SEC”) pursuant to Rule 406 of the Securities Act of 1933, as amended (the
“1933 Act”) relating to certain exhibits to be filed with the Registration Statement.

“Prospectus” means (i) the prospectus included in any Registration Statement, as amended or
supplemented by any prospectus supplement, with respect to the terms of the offering of any portion of the
Registrable Securities covered by such Registration Statement and by all other amendments and supplements to
the prospectus, including post-effective amendments and all material incorporated by reference in such
prospectus, and (ii) any “free writing prospectus” as defined in Rule 405 under the 1933 Act.

“Register,” “registered” and “registration” refer to a registration made by preparing and filing a
Registration Statement or similar document in compliance with the 1933 Act, and the declaration or ordering of
effectiveness of such Registration Statement or document.

“Registrable Securities” means (i) the Shares and (ii) any other securities issued or issuable as a dividend
or other distribution with respect to, in exchange for or in replacement of the Shares, whether by merger, charter
amendment or otherwise; provided, that, a security shall cease to be a Registrable Security upon (A) sale pursuant
to a Registration Statement or Rule 144 under the 1933 Act, or (B) such security becoming eligible for sale
without restriction (other than volume limitations) by the Investor pursuant to Rule 144 and without the
requirement to be in compliance with Rule 144(c)(1) (or any successor thereto) promulgated under the 1933 Act.

“Registration Statement” means any registration statement of the Company under the 1933 Act that covers

the resale of any of the Registrable Securities pursuant to the provisions of this Agreement, amendments and
supplements to such Registration Statement, including post-effective amendments, all exhibits and all material
incorporated by reference in such Registration Statement.

2.

Registration.

(a)

Registration Statements. Within 180 days following the date of this Agreement (the “Filing
Deadline”), the Company shall prepare and file with the SEC one Registration Statement covering the resale of all
of the Registrable Securities. Subject to any SEC comments, such Registration Statement shall include the plan of
distribution attached hereto as Exhibit A. Such Registration Statement also shall cover, to the extent allowable
under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of
additional shares of Ordinary Shares resulting from share splits, share dividends or similar transactions with
respect to the Registrable Securities. Such Registration Statement shall not include any Ordinary Shares or other
securities for the account of any other holder without the prior written consent of the Investor. Such Registration
Statement (and each amendment or supplement thereto) shall be provided in accordance with Section 3(c) to the
Investor prior to its filing or other submission. If a Registration Statement covering the Registrable Securities is
not filed with the SEC on or prior to the Filing Deadline, the Company will make pro rata payments to the
Investor, as liquidated damages and not as a penalty, in an amount equal to 1% of the aggregate amount invested
by the Investor for each 30-day period or pro rata for any portion thereof following the Filing Deadline for which
no Registration Statement is filed with respect to the Registrable Securities. Such payments shall constitute the
Investor’s exclusive monetary remedy for such events, but shall not affect the right of the Investor to seek
injunctive relief. Such payments shall be made to the Investor in cash no later than three (3) Business Days after
the end of each 30-day period (the “Payment Date”). Interest shall accrue at the rate of 1% per month on any such
liquidated damages payments that shall not be paid by the Payment Date until such amount is paid in full.

(b)

Expenses. The Company will pay all reasonable expenses associated with each Registration

Statement, including filing and printing fees, the Company’s counsel and accounting fees and expenses, costs
associated with clearing the Registrable Securities for sale under applicable state securities laws, listing fees, fees
and expenses of one counsel to the Investor and the Investor’s reasonable expenses in connection with the
registration, but excluding discounts, commissions and fees of underwriters, selling brokers, dealer managers or
similar securities industry professionals with respect to the Registrable Securities being sold.

(c)

Effectiveness.

(i)

The Company shall use reasonable best efforts to have the Registration Statements

declared effective as soon as practicable. The Company shall notify the Investor by e-mail as promptly as
practicable, and in any event, within forty-eight (48) hours, after any Registration Statement is declared effective
and shall simultaneously provide the Investor with copies of any related Prospectus to be used in connection with
the sale or other disposition of the securities covered thereby. If (A) a Registration Statement is not declared
effective by the SEC prior to the earlier of (i) five (5) Business Days after the SEC informs the Company in
writing that no review of such Registration Statement will be made or that the SEC has no further comments on
such Registration Statement or (ii) the 30th day after the Filing Deadline (or the 90th day if the SEC reviews such
Registration Statement) (the “Effectiveness Deadline”) or (B) after a Registration Statement has been declared
effective by the SEC, sales cannot be made pursuant to such Registration Statement for any reason (including
without

2

limitation by reason of a stop order, or the Company’s failure to update such Registration Statement), but
excluding any Allowed Delay (as defined below), then the Company will make pro rata payments to the Investor
then holding Registrable Securities, as liquidated damages and not as a penalty, in an amount equal to 1% of the
aggregate amount invested by the Investor for each thirty (30)-day period or pro rata for any portion thereof
following the date by which such Registration Statement should have been effective (the “Blackout Period”). Such
payments shall constitute the Investor’s exclusive monetary remedy for such events, but shall not affect the right
of the Investor to seek injunctive relief. The amounts payable as liquidated damages pursuant to this paragraph
shall be paid monthly within three (3) Business Days of the last day of each month following the commencement
of the Blackout Period until the termination of the Blackout Period (the “Blackout Period Payment Date”). Such
payments shall be made to the Investor in cash. Interest shall accrue at the rate of 1% per month on any such
liquidated damages payments that shall not be paid by the Blackout Payment Date until such amount is paid in
full.

(ii)

For not more than thirty (30) consecutive days or for a total of not more than sixty
(60) days in any twelve (12) month period, the Company may suspend the use of any Prospectus included in any
Registration Statement contemplated by this Section in the event that the Company determines in good faith that
such suspension is necessary to (A) delay the disclosure of material non-public information concerning the
Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests
of the Company or (B) amend or supplement the affected Registration Statement or the related Prospectus so that
such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein, in the case of the
Prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”);
provided, that the Company shall promptly (a) notify the Investor in writing of the commencement of an Allowed
Delay, but shall not (without the prior written consent of the Investor) disclose to the Investor any material non-
public information giving rise to an Allowed Delay, (b) advise the Investor in writing to cease all sales under such
Registration Statement until the end of the Allowed Delay and (c) use reasonable best efforts to terminate an
Allowed Delay as promptly as practicable.

(d)

Rule 415; Cutback. If at any time the SEC takes the position that the offering of some or all

of the Registrable Securities in a Registration Statement is not eligible to be made on a delayed or continuous
basis under the provisions of Rule 415 under the 1933 Act or requires the Investor to be named as an
“underwriter,” the Company shall use reasonable best efforts to persuade the SEC that the offering contemplated
by such Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as
defined in Rule 415 and that the Investor is not an “underwriter.” The Investor shall have the right to select one
legal counsel to review and oversee any registration or matters pursuant to this Section 2(d), including
participation in any meetings or discussions with the SEC regarding the SEC’s position and to comment on any
written submission made to the SEC with respect thereto. No such written submission with respect to this matter
shall be made to the SEC to which the Investor’s counsel reasonably objects. In the event that, despite the
Company’s reasonable best efforts and compliance with the terms of this Section 2(d), the SEC refuses to alter its
position, the Company shall (i) remove from such Registration Statement such portion of the Registrable
Securities (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and
resale of the Registrable Securities as the SEC may require to assure the Company’s compliance

3

with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company
shall not agree to name the Investor as an “underwriter” in such Registration Statement without the prior written
consent of the Investor. No liquidated damages shall accrue as to any Cut Back Shares until such date as the
Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions
applicable to such Cut Back Shares (such date, the “Restriction Termination Date”). In furtherance of the
foregoing, the Investor shall provide the Company with prompt written notice of its sale of substantially all of the
Registrable Securities under such Registration Statement such that the Company will be able to file one or more
additional Registration Statements covering the Cut Back Shares. From and after the Restriction Termination Date
applicable to any Cut Back Shares, all of the provisions of this Section 2 (including the Company’s obligations
with respect to the filing of a Registration Statement and its obligations to use reasonable best efforts to have such
Registration Statement declared effective within the time periods set forth herein and the liquidated damages
provisions relating thereto) shall again be applicable to such Cut Back Shares; provided, however, that (i) the
Filing Deadline and/or the Qualification Deadline, as applicable, for such Registration Statement including such
Cut Back Shares shall be ten (10) Business Days after such Restriction Termination Date, and (ii) the date by
which the Company is required to obtain effectiveness with respect to such Cut Back Shares shall be the 60th day
immediately after the Restriction Termination Date (or the 90th day if the SEC reviews such Registration
Statement).

3.

Company Obligations. The Company will use reasonable best efforts to effect the registration of

the Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will, as
expeditiously as possible:

(a)

use reasonable best efforts to cause such Registration Statement to become effective and to

remain continuously effective for a period that will terminate upon the earlier of (i) the date on which all
Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, and
(ii) the date on which all Registrable Securities covered by such Registration Statement may be sold without
restriction (other than volume limitations) pursuant to Rule 144 and without the requirement to be in compliance
with Rule 144(c)(1) (or any successor thereto) promulgated under the 1933 Act (the “Effectiveness Period”) and
advise the Investor promptly in writing when the Effectiveness Period has expired;

(b)

prepare and file with the SEC such amendments and post-effective amendments to such

Registration Statement and the related Prospectus as may be necessary to keep such Registration Statement
effective for the Effectiveness Period and to comply with the provisions of the 1933 Act and the 1934 Act with
respect to the distribution of all of the Registrable Securities covered thereby;

(c)

provide copies to and permit a counsel designated by the Investor to review each

Registration Statement and all amendments and supplements thereto no fewer than three (3) days prior to their
filing with the SEC and not file any document to which such counsel reasonably objects;

(d)

furnish to the Investor whose Registrable Securities are included in any Registration

Statement (i) promptly after the same is prepared and filed with the SEC, if requested by the Investor, one (1)
copy of any Registration Statement and any amendment

4

thereto, each preliminary prospectus and Prospectus and each amendment or supplement thereto, and each letter
written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from
the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion of any
thereof which contains information for which the Company has sought confidential treatment), and (ii) such
number of copies of a Prospectus, including a preliminary prospectus, and all amendments and supplements
thereto and such other documents as the Investor may reasonably request in order to facilitate the disposition of
the Registrable Securities owned by the Investor;

(e)

use reasonable best efforts to (i) prevent the issuance of any stop order or other suspension

of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order at the earliest possible
moment;

(f)

prior to any public offering of Registrable Securities, use reasonable best efforts to register

or qualify or cooperate with the Investor and its counsel in connection with the registration or qualification of such
Registrable Securities for the offer and sale under the securities or blue sky laws of such jurisdictions requested by
the Investor and do any and all other commercially reasonable acts or things necessary or advisable to enable the
distribution in such jurisdictions of the Registrable Securities covered by the Registration Statement; provided,
however, that the Company shall not be required in connection therewith or as a condition thereto to (i) qualify to
do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(f),
(ii) subject itself to general taxation in any jurisdiction where it would not otherwise be so subject but for this
Section 3(f), or (iii) file a general consent to service of process in any such jurisdiction;

(g)

use reasonable best efforts to cause all Registrable Securities covered by a Registration

Statement to be listed on each securities exchange, interdealer quotation system or other market on which similar
securities issued by the Company are then listed;

(h)

promptly notify the Investor, at any time prior to the end of the Effectiveness Period, upon

discovery that, or upon the happening of any event as a result of which, the Prospectus includes an untrue
statement of a material fact or omits to state any material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances then existing, and promptly prepare, file with
the SEC and furnish to such holder a supplement to or an amendment of such Prospectus as may be necessary so
that such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in light of the
circumstances then existing;

(i)

otherwise use reasonable best efforts to comply with all applicable rules and regulations of

the SEC under the 1933 Act and the 1934 Act, including, without limitation, Rule 172 under the 1933 Act, file
any final Prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under
the 1933 Act, promptly inform the Investor in writing if, at any time during the Effectiveness Period, the
Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Investor is required to
deliver a Prospectus in connection with any disposition of Registrable Securities and take such other actions as
may be reasonably necessary to facilitate the registration of the Registrable Securities

5

hereunder, and make available to its security holders, as soon as reasonably practicable, but not later than the
Availability Date (as defined below), an earnings statement covering a period of at least twelve (12) months,
beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the 1933 Act, including Rule 158 promulgated thereunder (for the purpose of this
subsection 3(i), “Availability Date” means the 45th day following the end of the fourth fiscal quarter that includes
the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the
Company’s fiscal year, “Availability Date” means the 90th day after the end of such fourth fiscal quarter);

(j)

with a view to making available to the Investor the benefits of Rule 144 (or its successor

rule) and any other rule or regulation of the SEC that may at any time permit the Investor to sell Ordinary Shares
to the public without registration, the Company covenants and agrees to: (i) make and keep public information
available, as those terms are understood and defined in Rule 144, until the earlier of (A) six months after such date
as all of the Registrable Securities may be sold without restriction by the holders thereof pursuant to Rule 144 or
any other rule of similar effect or (B) such date as there are no longer Registrable Securities; (ii) file with the SEC
in a timely manner all reports and other documents required of the Company under the 1934 Act; and (iii) furnish
electronically to the Investor upon request, as long as the Investor owns any Registrable Securities, (A) a written
statement by the Company that it has complied with the reporting requirements of the 1934 Act, (B) a copy of or
electronic access to the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q,
and (C) such other information as may be reasonably requested in order to avail the Investor of any rule or
regulation of the SEC that permits the selling of any such Registrable Securities without registration; and

(k)

if requested by an Investor, cooperate with the Investor to facilitate the timely preparation

and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to an
effective Registration Statement, which certificates shall be free, to the extent permitted by the Purchase
Agreements and applicable law, of all restrictive legends, and to enable such certificates to be in such
denominations and registered in such names as the Investor may request.

4.

Due Diligence Review; Information. If the Investor is required under applicable securities laws to

be described in a Registration Statement as an “underwriter,” the Company shall, upon reasonable prior notice,
make available, during normal business hours, for inspection and review by the Investor, advisors to and
representatives of the Investor (who may or may not be affiliated with the Investor and who are reasonably
acceptable to the Company) (collectively, the “Inspectors”), all pertinent financial and other records, and all other
corporate documents and properties of the Company (collectively, the “Records”) as may be reasonably necessary
for the purpose of such review, and cause the Company’s officers, directors and employees, within a reasonable
time period, to supply all such information reasonably requested by the Inspectors (including, without limitation,
in response to all questions and other inquiries reasonably made or submitted by any of them), prior to and from
time to time after the filing and effectiveness of such Registration Statement for the sole purpose of enabling the
Investor and its accountants and attorneys to conduct such due diligence solely for the purpose of establishing a
due diligence defense to underwriter liability under the 1933 Act; provided, however, that each Inspector shall

6

agree to hold in strict confidence and shall not make any disclosure (except to the Investor) or use of any Record
or other information which the Company determines in good faith to be confidential, and of which determination
the Inspectors are so notified, unless (a) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement or is otherwise required under the 1933 Act, (b) the
release of such Records is ordered pursuant to a final, non-appealable subpoena or order from a court or
government body of competent jurisdiction, or (c) the information in such Records has been made generally
available to the public other than by disclosure in violation of this or any other Transaction Document.

Notwithstanding the foregoing, the Company shall not disclose material nonpublic information to the

Investor, or to advisors to or representatives of the Investor, unless prior to disclosure of such information the
Company identifies such information as being material nonpublic information and provides the Investor, such
advisors and representatives with the opportunity to accept or refuse to accept such material nonpublic
information for review and the Investor wishing to obtain such information entered or enters into an appropriate
confidentiality agreement with the Company with respect thereto.

5.

Obligations of the Investor.

(a)

The Investor shall furnish in writing to the Company such information regarding itself, the
Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it, as
shall be reasonably required to effect the registration of such Registrable Securities and shall execute such
documents in connection with such registration as the Company may reasonably request. At least five
(5) Business Days prior to the first anticipated filing date of any Registration Statement, the Company shall notify
the Investor of the information the Company requires from the Investor if the Investor elects to have any of the
Registrable Securities included in such Registration Statement. The Investor shall provide such information to the
Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if
the Investor elects to have any of the Registrable Securities included in such Registration Statement.

(b)

The Investor, by its acceptance of the Registrable Securities, agrees to cooperate with the

Company as reasonably requested by the Company in connection with the preparation and filing of a Registration
Statement hereunder, unless the Investor has notified the Company in writing of its election to exclude all of its
Registrable Securities from such Registration Statement.

(c)

The Investor agrees that, upon receipt of any notice from the Company of either (i) the
commencement of an Allowed Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event pursuant to
Section 3(h) hereof, the Investor will immediately discontinue disposition of Registrable Securities pursuant to
any Registration Statement covering such Registrable Securities, until the Investor is advised by the Company that
such dispositions may again be made.

(d)

The Investor covenants and agrees that it will comply with the prospectus delivery

requirements of the 1933 Act as applicable to it or an exemption therefrom in connection with sales of Registrable
Securities pursuant to any Registration Statement.

6.

Indemnification.

(a)

Indemnification by the Company. The Company will indemnify and hold harmless the

Investor and its officers, directors, members, employees and agents, successors and assigns, and each other
person, if any, who controls the Investor within the meaning of the 1933 Act, against any losses, claims, damages
or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement or omission or alleged omission of any material fact contained in any
Registration Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof,
and will reimburse the Investor, and each such officer, director or member and each such controlling person for
any legal or other documented, out-of-pocket expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company
will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or
is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by the Investor or any such controlling person in writing specifically for
use in such Registration Statement or Prospectus, (ii) the use by the Investor of an outdated or defective
Prospectus after the Company has notified the Investor in writing that such Prospectus is outdated or defective or
(iii) the Investor’s failure to send or give a copy of the Prospectus or supplement (as then amended or
supplemented), if required (and not exempted) to the Persons asserting an untrue statement or omission or alleged
untrue statement or omission at or prior to the written confirmation of the sale of Registrable Securities.

Indemnification by the Investor. The Investor agrees, severally but not jointly, to indemnify

(b)
and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees,
shareholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses,
claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement
of a material fact or any omission of a material fact required to be stated in any Registration Statement or
Prospectus or preliminary Prospectus or amendment or supplement thereto or necessary to make the statements
therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in
any information furnished in writing by the Investor to the Company specifically for inclusion in such
Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of the
Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by the Investor in
connection with any claim relating to this Section 6 and the amount of any damages the Investor has otherwise
been required to pay by reason of such untrue statement or omission) received by the Investor upon the sale of the
Registrable Securities included in such Registration Statement giving rise to such indemnification obligation.

(c)

Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder
shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification
and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory
to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to
employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel

8

shall be at the expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses,
(b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably
satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its
counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims
(in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate
counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the
defense of such claim on behalf of such person); and provided, further that the failure of any indemnified party to
give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the
extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any
such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding
in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for
all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, which
shall not be unreasonably withheld or conditioned, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified
party of a release from all liability in respect of such claim or litigation.

(d)

Contribution. If for any reason the indemnification provided for in the preceding paragraphs

(a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly
specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified
party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative
fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations.
No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be
entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the
contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the
proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the
amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to
such contribution obligation.

7.

(a)

Amendments and Waivers. This Agreement may be amended only by a writing signed by

agreement is furnished to the Company within a reasonable time after such assignment; (ii) the Company is within
a reasonable time after such transfer or assignment, furnished with written notice of (A) the name and address of

securities by the transferee or assignee is restricted under the 1933 Act or applicable state securities laws; (iv) at

transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein

Agreement.

(d)

Company (whether by operation of law or otherwise) without the prior written consent of the Investor, provided,
however, that in the event that the Company is a party to a merger, consolidation, share exchange or similar
business combination transaction in which Ordinary Shares are converted into the equity securities of another

deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer

after giving effect to such transaction.

Plan of Distribution

We are registering ordinary shares previously issued to permit the resale of these ordinary shares by the holders of
the ordinary shares from time to time after the date of this prospectus. We will not receive any of the proceeds
from the sale by the selling shareholders. We will bear all fees and expenses incident to our obligation to register
the ordinary shares, except that, if the ordinary shares are sold through underwriters or broker-dealers, the selling
shareholders will be responsible for underwriting discounts or commissions or agent’s commissions.

The selling shareholders may sell all or a portion of the ordinary shares beneficially owned by them and offered
hereby from time to time directly or through one or more underwriters, broker-dealers or agents. The ordinary
shares may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at
varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions,
which may involve crosses or block transactions,

● on any national securities exchange or quotation service on which the securities may be listed or quoted at

the time of sale;

● in the over-the-counter market;

● in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

● through the writing of options, whether such options are listed on an options exchange or otherwise;

● ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

● block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell

a portion of the block as principal to facilitate the transaction;

● purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

● an exchange distribution in accordance with the rules of the applicable exchange;

● privately negotiated transactions;

● short sales;

● sales pursuant to Rule 144 of the Securities Act;

● broker-dealers may agree with the selling shareholders to sell a specified number of such shares at a

stipulated price per share;

● a combination of any such methods of sale; and

● any other method permitted pursuant to applicable law.

If the selling shareholders effect such transactions by selling ordinary shares to or through underwriters, broker-
dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts,
concessions or commissions from the selling shareholders or commissions from purchasers of the ordinary shares
for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or
commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the
types of transactions involved). In connection with sales of the ordinary shares or otherwise, the selling
shareholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of
our ordinary shares in the course of hedging in positions they assume. The selling shareholders may also sell
ordinary shares short and deliver ordinary shares covered by this prospectus to close out short positions and to
return borrowed shares in connection with such short sales. The selling shareholders may also loan or pledge
ordinary shares to broker-dealers that in turn may sell such shares.

The selling shareholders may pledge or grant a security interest in some or all of the shares of our ordinary shares
owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties
may offer and sell the ordinary shares from time to time pursuant to this prospectus or other applicable provisions
of the Securities Act, amending, if necessary, the list of selling shareholders to include the pledgee, transferee or
other successors in interest as selling shareholders under this prospectus. The selling shareholders also may
transfer and donate the shares of our ordinary shares in other circumstances in which case the transferees, donees,
pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling shareholders and any broker-dealer participating in the distribution of the ordinary shares may be
deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts
or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts
under the Securities Act. At the time a particular offering of the ordinary shares is made, a prospectus supplement,
if required, will be distributed which will set forth the aggregate amount of shares of our ordinary shares being
offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts,
commissions and other terms constituting compensation from the selling shareholders and any discounts,
commissions or concessions allowed or reallowed or paid to broker-dealers.

Under the securities laws of some states, the ordinary shares may be sold in such states only through registered or
licensed brokers or dealers. In addition, in some states the ordinary shares may not be sold unless such shares have
been registered or qualified for sale in such state or an exemption from registration or qualification is available
and is complied with.

There can be no assurance that any selling shareholder will sell any or all of the ordinary shares registered
pursuant to the registration statement, of which this prospectus forms a part.

The selling shareholders and any other person participating in such distribution will be subject to applicable
provisions of the Exchange Act, and the rules and regulations thereunder, including, without limitation,
Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the ordinary
shares by the selling shareholders and any other participating person. Regulation M may also restrict the ability of
any person engaged in the distribution of the ordinary shares to engage in market-making activities with respect to
the ordinary shares. All of the foregoing may affect the marketability of the ordinary shares and the ability of any
person or entity to engage in market-making activities with respect to the ordinary shares.

We will pay all expenses of the registration of the ordinary shares pursuant to the registration statement of which
this prospectus forms a part, including, without limitation, SEC filing fees and expenses of compliance with state
securities or “blue sky” laws; provided, however, that the selling shareholders will pay all underwriting discounts
and selling commissions, if any. We will indemnify the selling shareholders against liabilities, including some
liabilities under the Securities Act, or the selling shareholders will be entitled to contribution. We may be
indemnified by the selling shareholders against civil liabilities, including liabilities under the Securities Act, that
may arise from any written information furnished to us by the selling shareholders specifically for use in this
prospectus or we may be entitled to contribution.

Once sold under the registration statement of which this prospectus forms a part, the ordinary shares will be freely
tradable in the hands of persons other than our affiliates.
